i rarely use paypal but now i wanted to because of a family emergency. i changed my phone number recently and forgot about the 2 factor authentication and now i cannot log into my account. its difficult to talk to customer service about my issue unless i log in but to do that i need my old phone number. it's so ridiculous. i tried talking to them on facebook but the response time takes forever. if you need to urgently send money for a family emergency, dont count on these guys!
