Frustrating Customer Call Centre service

Frustrating customer call centre service. It is extremely frustrating to get through to the Standard Bank Call Centre. After waiting, at times for 21:54 minutes, numerous drop calls and being sent from one department to another, I just could not get any help from Standard Bank. All I wanted was a follow up on a Query, which they closed, without the feedback as I was promised. Just getting through is frustrating, as they go on, for example about "Grid failure exclusions" when they could have listed it under another option. Consequently, you are forced then to listen to information you do not need, costing time and airtime, etc. Also, if you choose the options provided in the intro, you would be directed to the same number. The consultant on the other end keeps saying that you have come through to the wrong desk, even though you have followed their instructions as given, and consequently you have to be re-directed and stand yet, in another queue, waiting for service. Can't Standard Bank please correct this!!! Its frustrating just trying to get through and then be subjected to a flawed call-in service, Annoying. Please can anyone from Standard Bank just give me feedback on my query?
