Cannot make or receive calls and load or check airtime

<p>Since I had complained about the disappearing data, which took a week to solve, now I cannot load airtime, make or receive any calls. I could browse the net and go into social networks when I had data and receive sms'. I called the customer care with another phone and they said there is no restrictions or sim swap done, my sim is active but I should do a sim swap because my SIM card isn't working. I asked how that is possible because she just told me my sims active and shows no problem but I should get a sim swap because she doesn't know why I cannot receive or make calls and load or check airtime. I need answers because I have missed important opportunities because I couldn't receive or make calls. Seriously annoyed and I need to know what's going on. So disappointed in Vodacom and it's worse that I even have shares with them. alternative number ********** </p>
