Disgusting service from STANDARD BANK!

When I was unemployed Standard bank closed stopped my RCP account so no transactions would take place, then I started working and started paying them back to which the account was still stopped but payment was being received. I then settled teh account on October 2017 and sent them POP as they refused to give me a settlement letter, this is how they operate and Ihad to make the payment the same day and to reflect in their account that day otherwise interest would be added to the account. To which I did. I then Asked for the account to be closed which they didn't bother to do and they still charged me bank charges and interest to a zero balance account and handed me over to legal. How do you charge to interest and bank charges to a ZERO BALANCE???? Again this is how STANDARD BANK OPERATES!!! I have called and complained and they still have done absolutely nothing!!!!! Great Job Standard Bank, good to know you guys care about your clients and have such wonderful ethical standards!!!!!! WELL DONE!!! You a great example to other banks!!! And thank you so much for ruining my credit record!!!! Because you didn't do YOUR JOB!!!!
