This bank is a ****

I requested account closure and deleted app 4 years ago. 2 days ago friend tried to refer me and told me that i was already a member. I thought it was impossible. Downloaded the app and tried to log in. My balance was - R12550. They have been debiting a dormant account for going on 5 years. Never received 1 phone call, 1 sms or even an email.. Am i the only one this has happened to? Customer care was very good. We spent 10mins laughing about how bad the situation is. She said I am more than willing to close account after I settle the R12550. She had a great sense of humour to be fair. Netflix need to do a documentary on this ****py bank. Regards
