NO SERVICE - MOBILE UPGRADE ?? BAD SERVICE

Recieved call from telkom mobile that i can upgrade 2 of my contracts. I went to Summerset Mall branch that is the closest as we stay 60km from the nearest Telkom branch. We signed contracts and telkom sales person said we should wait 3 hours and come back to fetch the phones. After hanging around 3 hours he said there was a problem and that he would get back to us asap. We waited till the next day and no call from them. We then drove all the way back to Somerset West from Kleinmond after 2 days . The sales rep then told us he is still waiting to find out whats happening and will get back to us the following day. Again no comminacation from him. We also emailed him several times with no response. They do not even have a number to dial at the branch ?? The number they gave goes to voice mail and no one ever gets back to you. We then drove to the branch again after 5 days of no feedback. Then the rep said there systems are off and he can only phone us back the next day. Same answer still no sullotion , i then asked for the manager and same answer as always ,manager is not available today. I then went back again yesterday were the sales rep was out . No one could help ???
