Still being ignored by Standard Bank

On 18 February I raised a complaint about a cheque that was paid into my account but rejected by Standard Bank. First I was told there was no information on the cheque, then that the cheque was for an amount paid in during September 2014, then a complaint was raised (ref ***) which was supposed to be resolved by the 24th of Feb, but I received NO word from Standard Bank, after which I raised the complaint again, waited another week, raised the complaint via HelloPeter, then had to phone to Complaints division AGAIN and was told my mail had been sent to a wrong e-mail address (how *********** IS Std Bank exactly?!) and then finally a week later received an e-mail stating that the drawer of the cheque's account had been closed. I have confirmed with ABSA: the account is active and operational and there IS money in the account. Can you REVERSE the cheque amount, REFUND me the interest lost, or come up with the REAL reason for dishonouring the cheque before Xmas, perhaps??? Your adverti*****ts make me laugh - moving forward: NOT AT ALL!! Thank God I also have an account with Investec: Investec knows how to treat a chartered accountant and delivers excellent service, consistently
