allow me to say that i am indeed a dumbass and i haven't stopped worrying about this since it happened. i made a very stupid decision and i wish i could have been smarter and less timid.

so, today i was moving into a new place and doing some cleaning with my girlfriend. i'm vigorously scrubbing the bathtubs when i hear a knock on the door. girlfriend answers it and an older man stands at the doorway and asks for a francis or somebody. we mention that we don't know such a person and he hands us a flier for the local internet and cable company (frontier communications, which is basically version internet but with a different name). he asks us if we are interested in getting internet, phone or cable service. i respond with a yes after some hesitation because i was indeed looking into calling the local internet company and setting up an account within the week or so. he gives me and the girlfriend his sales pitch saying that it's no contract. he mentions that he also sells service for the other competing cable company (mediacom) in our area. i notice the badge on his lanyard and it's got his picture, name and mediacom's logo on it (basically his id badge). anyways, it's a no contract deal with a fixed price for a year (i know, they will most likely raise it later on. i don't have much of a choice though since they've got a monopoly going on here.) anyways, he says this deal comes with a free/no fee for modem and wifi (mediacom charges 5$ extra in fees for both) internet that comes from the phone line. my mom has used frontier before so i know that this is indeed how they do things. his name is printed on the flier as well as a number and the company logo. sounded like a good deal but i was starting to get kinda suspicious. but i agreed to it because i really wanted to take care of getting the internet soon. i asked him questions about has fast it was and such, and he seemed to know a fair bit. so that eased my suspicions some. he asks for my info and i give him my first and last, phone number, the usual contact i to. then he asks for my social. and i hesitate and tell him i can't do that. he works to convince me that it's okay and that it's needed to set up the account and such. i still refuse and he tells me he's been doing this for about 15 years and has gathered more than 400 ss numbers and that he hasn't done anything with those and that he wouldn't have anything to gain from it. i was still hesitant and he told me he didn't bother to ask any of the older people because they would never give it to him since that's what they are told to do. i don't know, i'm not feeling good about it. but because i am so stupidly timid, i caved and gave him my ss number. he says the internet just needs it to run it and see if everything checks out fine. he aslso asks for a security question date of birth and a pin and i have him stuff that doesn't match anything i have for a bank or anything. i'm still feeling awful at this point and he tells me that if it would make me feel better, he would call it in and i could scratch off the number on the paper. he calls it in and let's me scratch it off and says i should receive a call back around monday since it's the weekend and they most likely won't put in the info until the next business day. i'm dying inside at this point and he limps his way outside and says he's gonna look for the phone line. he's groaning about his knees or some shit and after about a minute he says he spots it and says they will most likely call me on monday and come to hook things up then i'll receive my modem a day later by ups. he bids me goodbye and goes around putting fliers a peoples doors and i start freaking out the more i think about it. i just did something very stupid and start to try to confirm my suspicions by thinking about they way he talked and acted. he was an older man who was heavyset with medical problems. he could be using that as a tactic to gain my sympathy and appear less threatening. he checked the place out, and knows quite a bit about me now. he saw the moving boxes and stuff i had. i called frontier and they confirmed that they had hired an external service to go door to door and sell their service. this calmed me down some but i still wasn't feeling very good. i went outside and saw that he was leaving. he waved goodbye to me and i pulled out my phone and sneakily took a picture of his car and captured his license plate number. i conveyed my concerns to my girlfriend and she thinkss i'm being paranoid. i tried to call the cable company again to ask if they were asking for ss numbers and such but since it was after business hours i didn't get through to anyone. i'm freaking out and wondering what i should do to check and see if my info is being used. i plan to try to call again tomorrow and see if my account is set up since i saw online that comcast had done something similar and although shady, people saw that their accounts were created.

i've never felt so stupid in my entire life. trying to do damage control but it's late at night and there's nothing i can do at this point.
