Struggling with Tymebank.

Peter Tymebank is just the worst bank ever, you struggle to communicate with them when you are having issues.I opened my account online, money was deposited to my account, I have not yet received my card so I was not able to withdraw. I changed my cellphone number due to theft of my cellphone that's why I was unable to receive any notifications.Now I have a new device tried to activate my app account blocked call them they argue and say it's not my account and there's is no money in what do I do????????.
