CELL PHONE SHOP WITHOUT SIM CARDS

MTN has gone from being one of the first, biggest and best cell phone providers in the country, to being completely useless. i have been with MTN for the last 10year+. and if it is not bad enough that for the last few months it is basically impossible to buy data bundles from any MTN store, they now also don't have sim cards. I am a contract customer and my brand new upgrade (2 months old) got ****** out of my bag this morning. it takes me 45 minutes to get through to the call centre to stop my sim card. They tell me to do a sim swop at any MTN store, only to find that after standing in a queue at Cresta branch for an hour, they do not have sim cards in stock. My phone is my business. Now I not only have to pay for a contract that i cannot use, but I am also losing business (and money) because i cannot get a sim swop. MTN, you have been great in the past, but i have gone from having 3 contract with you, to only having one. And when this one runs out, i am definitely moving to VODACOM!
