MTN very poor service.

I received a call from a sub contractor in Umhlanga Durban. Ignition Group who I did not realise sub-contracts to MTN talked me into saving money with the same benefits. My amended contract differed from the contract I have had for many years. I received airtime money, no SMS's or data. I have been trying to revert to my old contract for two weeks. Three trips to the Mall of the North MTN no joy. was told to call 135. They said I must contact Ignition in Durban. After numerous calls I spoke to a lady there who would not give her name. She promised after 24 hrs my contract for ********** 329 would revert to the original. Still nothing has happened.. MTN must please wake up. Derek Ponsford
