My Last Straw With Telkom Mobile

I've finally had enough of Telkom Mobile.<br> We took out multiple business contracts with them in September 2013, but are always having issues with our wifi, cellphone signal and now, sim cards.<br> These are business phones, so it is absolutely essential they are always on, always working.<br> Now my sim card stops working. I call the call centre to complain about my non operational sim card, only be to told I need to do a sim swop...of which I need to fit the bill for.<br> Why do I need to pay for something that went wrong with a Telkom Moblie product?<br> Out of all the contracts I have, this is the first time I need to pay for a faulty product.<br> <br> I have no choice but to get a new sim card, because our business depends on cell phones in working order, but I am done with Telkom Mobile
