********* disguising as a Bank

I had a credit card with Standard bank blue bin, after some serious harassment for payments I eventually closed the account, my last payment was a R26 000, after making this payment I asked for the settlement letter and a letter confirming that my account has been closed, I received both the letter, I asked because I could sense I was dealing with ****** who only see clients a milk ***s. A week ago I got a call saying I am owing, the lady I spoke to said it is a mistake and she is logging a call to have the account close, she even gave me a reference number ***, I also got an SMS saying this has been resolved, today I get an sms saying my account is handed over. I dont have time for this nonsense, I left your bank long time ago, I want nothing to do with your ******** activities. I want a call from a manager explaining why they are trying to ****** money from...Standard is the most innovative bank with ideas of how to ***** from their customers.
