Worst service at MTN

On the 4th of April 2018 I app**** for a contract (at MTN Southgate) and it was approved and I collected it on the 7th of April 2018. Kholiwe, the consultant, gave me the phone and confirmed that the swim swap is to be done in 15 minutes time. I waited until Tuesday, the 10th of April 2018 and the phone was still not functioning because sim swap hasn't been done, I was then advised by Daphne the other consulted from MTN Southgate (telephonic-ally) to return the phone so the contract could be cancelled because there is system failure. The phone was returned on Tuesday, the 10th of April 2018 and was advised that it will only take 3 days for the contract to be cancelled.

I have been calling (MTN customer care) and doing a follow up since nothing is being done, I even went to the head office on the 14th of April 2018, Zitha the consultant at the head office explicitly said that there is nothing that he could do. My contract is not cancelled as yet and I received benefits in my old sim card as to prove that my contract is not cancelled.

Yesterday (19 April 2018), I called customer care, Thamsanqa was the guy I spoke to and he told me that they wont cancel my contract and they will debit money from my account, "it is not our problem that you returned the phone, we are going to deduct money from your account for 24 months" he said. I then spoke to his supervisor and he referred me to the store, I called the store and the supervisor said he can't assist me with regards to the cancellation of the contract because they do not have access to do so.

Now I don't Know what to do.
