Hi, I cannot log in to my Paypal account because it is asking me for an old phone number to receive a call or text message. I have recently moved abroad and my old phone is no longer in use. How am I supposed to be able to access my account? I was also told to call to resolve this issue but the international charges will be a nightmare on the salary I am on in my new country. Can we please resolve this by email? If you are worried about security concerns you can ask me anything and I will reply the best I can. I haven't used Paypal in quite a while and even then for very small transactions. I believe the last time I logged in was probably around August ****. The last withdrawal I made was about $** or something around this amount. I don't think I've ever had more than $*** or so in my account. Right now I have a deposit of $***.** from a company named italki pending. Please help me on this issue as this is my only income and I need access to it ASAP. Thank you.**Kind Regards,*Darren Colgan
