MTN **********

I have been on a smart xs contract with MTN, it is affordable and I was happy. A MTN agent called me and asked if I want to move to a my mtn choice 20gb contract for the same amount, R99/month. I agreed that it sounded fine and agreed to the change. But since 10/06 I have been receiving invoices for ±R1132/month. After various calls, emails I found out that this upgrade was done through Mobile plus or Ignition ---- I have been **** to, they **** and told me they where MTN, they **** about the amount payable. You know this is *****, right? After a few calls to Mobile plus they assured me that MTN has cancelled and reverted my contract back to the smart xs. Again phoning and emailing MTN they told me that they do not know about this, the contract still stands because 'i have agreed to this'..... WHAT? This is MTN's responsibility to solve, but no help, I do not know what do. Do yourself a favour, do not renew your contract with MTN --- customer service poor, they lie, departments do no talk to each other and are unwilling to go the extra mile.
