Disgusting ******* Service

A month ago my contract, 2 phones was cancelled by my Son whose name was on the contract. 1 was done and the other not? Last Thursday I received an Mtn billing sms? My Son and I went to the Mtn outlet in Retail Park Beacon Bay to query. The person whom was to have initially canceled the contract was not on duty but the lady whom saw us was really friendly and apologetic. We requested immediate cancellation and was informed that all airtime, sms's and data would be lost. The contract we were on gave us airtime and sms's so we had to purchase our own data. I informed the staff member that Mtn may take the airtime and sms's but may not take the data as I had purchased it. I was informed that that was Mtn's policy / system and all would be taken. I asked and was informed that Mr Nyati was the CEO so with my phone called Mtn Head Office. Naomi answered and blatantly refused to put me through to Mr Nyati or his Pa as I requested. I then was placed on hold for a total of around 20 minutes where a lady Maze ( spelling ) once again explained the Mtn system to me. I mentioned that it would be ******** to take something from me which I paid for. I was assured to be contacted? ***.
