ABSA Banking

I banked with ABSA since 2003. 20 years later I decide to move banks, the best decision I could have made. It is well over 2 years that I have moved banks and today I get an email from credit collections saying my account is overdrawn and I need to settle it and the account will be closed. Mind you, this is the second time, settle the account and the account will be closed. No statements received in 2 years, no bank card, no access to ABSA app. They just waited 2 years to let me know oh wait the account is still open and now owe over R1000 in charges.
