Do Not Bank with Standard if u have a choice

I withdrew R1300 in Onitsha Nigeria from my Standard Bank account in SA 0n 16/8, however I did not receive the money but the amount was deducted from my credit card account. I contacted the local bank and they informed me this happen regularly - my account will be credited within 2 weeks which did not happen. I contacted Stanbic on 16/09 and they referred me to SA. I phoned Card Division and they promised to give me feedback, did not happen. I logged complain with Customer Resolution Centre Ref ***3 on 4/11 received no reply. A second complaint was logged with the CRC and no response. Eventually I reported the matter on 17/2 with Hello Peter and on Std Bank Facebook page. Got an e-mail from Thabisele Nxumalo to say they will investigate and revert. It is a month later and to no surprise I have not heard anything yet again. Standard Bank can keep my money I don't want it anymore as I will be closing my accounts with them after 30 years. It is purely a matter of principle for me that a bank provide such appalling service and get away with it. Just want to warn potential clients of what will happen when things go wrong with their accounts.
