Shocking service from Standard Bank

I have 2 money market/call accounts with Standard Bank which earn a fair amount of interest. Standard Bank do not automatically forward tax certificates. The website indicates tax certificates can be obtained via the online banking app. I tried but it obviously only caters to current accounts not money market accounts. I then phoned customer services and after 15 minutes my call was eventually answered. I was subsequently verified and the certificates were ready to be sent by the consultant only to find it was not possible because my email address on record with Standard Bank is incorrect. My email service provider is mweb and my email address is ***. Standard Bank has it as *** So obviously it was incorrectly captured when I opened the accounts. Anyway surely they should know by now that wmeb email accounts end with .co.za and not with .com. The consultant would not correct my email address but indicated I have to go to the nearest Standard Bank branch to get it corrected. That will be another 2 or 3 wasted hours as i will have to wait in a queue being served by too few consultants. Last time I waited over 2 hours in a queue to fetch my replacement debit card. Not to mention the cost to travel to the branch. All I can say is that I extremely dissatisfied with their *********** service. I have complained several times before this on Hellopeter and never has anyone from Standard Bank ever contacted me. I think it is time for me to try out another bank. Can't be worse than this.
