Unacceptable service from Standard Bank

23 April 2022 receive a SMS from Standard Bank for thegamevalley R 685.40 bought on my credit card. Reply to the SMS that I have not bought anything from this company and do not know them. SMS undelivered. Phone the bank and advise Tracey this is a ********** transaction. She advises that she cannot stop or reverse the transaction and I have to wait for two days to reflect on my credit card statement. Phone the bank on 26 April and consultant advises that I should complete a dispute form. 27 April I receive an e mail that there is not enough details for them to process my request, they require description of goods, delivery date and proof that I have communicated with the company.On the dispute form I again explained that I do not know the company and cannot engage with them as I have no details. Sent e mail and on 12 May 2022 Siphiwe Tshabala said he referred this to the ***** department and will stop my credit card and request a new one. On Saturday 21 May 2022 I again phone the Standard Bank ***** line and spoke to Connie. No ***** case was opened and no new credit card requested. She opened a ***** case no ***. On Monday 23 May I received a SMS that my ***** case was on hold due to uncleared transaction on my credit card. Tuesday 24 May I received the same SMS. This is not correct as all my purchases reflected on my credit card statement as on 13 May 2022 and I have not used it since as it was blocked. I have tried to phone the bank on *** and used all my talk time minutes, as they are always experiencing high call volumes. They also do not respond to my e mails. There is no way I can communicate with them and nothing has been done to resolve my query.
