MTN BRANCH MANAGER IS APPAULING AND A BULLY!!

I have had the worst experience with MTN. Firstly I bought a new sim card from Woolworths in Alberton as the MTN Alberton city branch had no stock. The teller at Woolworths confirmed she had Rica my sim as I wanted to do a sim swap to keep my cellphones number that I have had since 1996. Within the next couple of days I had received phone calls from a few people including the vet as my dog just went under a surgical procedure and was a follow up call. When I tried to review the balance on my account I realized my sim was not rica when the message came through advising that I should rica my sim. I went to the MTN branch at four days mall and was absolutely appalled by the service and treatment I received from the branch manager! I was extremely upset having to drive to another branch to rica my sim again when I had already done so. I was cut off the network so my children who reside overseas could not get hold of me nor the vet. The manager was extremely rude and told me not to raise my voice or she would not help me! I was powerless to her as I obviously needed her help. After she spoke to customer services the woman on the phone told her she needed a number behind my sim. So she advised me to go to the vodacom repair centre downstairs to help remove my sim card as it was stuck and I had to pay R253.00. When i returned she spoke with another person from customer care that advised they dont actually need that number on my sim! I was horrified that i just wasted my money, the manager just shrugged and said well atleast you dont have to pay for another sim?? A sim card cost around R4!!! After all this she said i could loose my number because she cannot guarantee my sim will work with my old number because if you dont use your number for 3 months head office turns off your number?? Where did anyone ever let me know this?? I cannot loose my number or my children cannot get hold of me nor all my banks, accounts etc that i have registered this number with for soooooo many years! Now i am in my way to head office to take this further, without a phone for directions. If my car breaks down or anything happens I cannot call anyone to help me! This is massively aggravating and appalling!!
