MTN Centurion Mall is the WORST branch to visit !!!

I have an account with MTN ! I went in on Saturday to get a hand set added to my account at mall of the south MTN, then they told meit is approved! Thereafter they went offline ! So i told them to cancell it ill go to another branch. ! Monday I went to the big MTN in Centurion Mall, after 4 hours of waiting they told me they forgot to upload the ID so they need to reload and wait for approval i should come back the following morning. I went back the Tuesday morning just to find out that they have not done anything yet, they told me they still need to call in to get approval, i should come back the afternoon, I went back Tuesday afternoon and they still had no answer for me and they are all quite rude ! I told them its been 2 days now surely they cant take that long, the guy who assisted me told me he will try his best to get it done and call me before end of business. He never called me and im still waiting for an answer ? 3 days just to get a device and a sim ported ? this is ridicules !
