Bad Service Experienced by Standard Bank

I have been a good paying up customer of Standard Bank for many, many years now but of late the service has changed... I have repeatedly tried over a period of time to re-new my credit card to no avail. Each time it gets sent to an inconvenient distance to what I had requested. To date I have paid my last amount of R718.83 and hereby request that you close my account due to lack of good service.
