Two Requests and two no replies

I have tried twice to get MTN Business to return calls, I have been to the Greenstone store, the Karaglen store, I even tried to do a request online tonight, and the website kept popping up "not responding" In general my experience with MTN has been grand over the last 20 years that I have been with them. I small billing issue now and then, but it was rectified ASAP. I would like to now upgrade my phone, look at my 21st year contract if I would like to do any changes. Visiting both stores, i was greeted and advised, but never given an actual answer as to when and where and how much. So this I would like to know from MTN, is it at all possible for an account manger or service manager to contact me so that I can have this cleared. I am really disapointed in the service that "most " MTN stores provide now a days. Most appreciated, Loyal for 20 years
