So i made a purchase, i bought Next Ear Buddies Wireless earphones with sweetcoins. All i had to do was to pay the post services, around 15 Euro. No problem, only that i couldn't pay because of an error. I try again, then i get a SMS from my bank to ask if i autorize the pay, because they thought that this is a scam. I said yes and after i tried again, they froze my card.What now??
