Second line linked to my phone and I am being bill

About a year ago I complained to MTN about a R4000 account on my R75 top up package. After standing 2 hours in a line and talking to several people, our local branched just pulled up their shoulders and said it was for data usage and they will look into the problem. Three months later still no response with monthly bills far over the contract amount. We made monthly emailed enquiries to no avail.<br> I stopped payment and MTN suspended all my other contracts with them. <br> Since we run a Security Company and my premi-cell lines was among the contacts, they effectively stopped my business. I was forced to pay for the data I never used and them handed MTN over to my legal team. Now they ignore all efforts of my attorney to communicate with them.<br> We found out that the contract in question had one number for calls but when I want to use WhattApp, it showed a different cell number. I called this number and someone unknown answered it. They refused to give me their details.<br> It seems MTN is trying to force their RSA clients to pay their $3.4Bln Nigerian fine. As my contracts expire, I am cancelling them one by one and move over to Vodacom.
