PUTRID SERVICE FROM ONE2ONE TFG MOBILE

I called TFG mobile with regards to an airtime contract they offer. I needed the airtime for a Vodacom number that I already had, They had to port my number to MTN before they could give me the contract. They first send me the wrong sim which takes a few days to get to me. Sim being wrong because it came up as unregistered sim. They send me the second sim which takes forever to activate, when it does activate, its just for an hour. I use this phone for business and its losing me a lot of money and causing me a great inconvenience. The problem is that my number is now not active and customers are unable to reach me. Its nearing two weeks now and my sim is off. LETS SEE ONE2ONE RUN THEIR BUSINESS WITHOUT PHONES SINCE THEY EXPECT ME TO RUN MINES WITHOUT ONE.. Numerous calls to their call centre, non return of calls, false promises , STILL NO RESULTS. To make matters worse they have billed me and I have paid already for something I never received. I have asked to speak to a manager, the best they could give me was a team supervisor. Managers don't take calls only emails. This is the most pathetic service I have ever received.
