Can't cancel contract **********ly sold to me within 10 day cool down period

After an MTN Agent sold me a contract, blatantly lying to me to get the sale and I realised it afterwards by MTN and their agent telling me it was the case, I can't cancel the contract even though and MTN agent, MTN themselves and I tried to do it within the 10-day cooling off period. Reference numbers were given, it all recorded yet neither the MTN agent of MTN's cancellation department (on 808) can get any feedback or support from MTN Channel Query department. I realised I have been conned on day 8 after agreeing to do it and had the MTN Agent logging a cancellation request. On day 10 MTN (808) also did the same. MTN Channel Queries are not responded for 8 days in a row and no one seems to be able to chat with them to demand an answer. I am based in Cape Town and MTN say one has to go to their office in Johannesburg to sort it out. I am now stuck for 2 years with a contract (where no phone was given) that I was **********ly spoken into, lying to me about it and even MTN and their agent saying I was misinformed and talked into accepting this contract under false pretense so that the agent who sold it to me could get a commission at all cost. No manager can escalate it to no other manager. I will appreciate if MTN can resolve the matter for me and I be reverted to my previous contract so I can take a month to month contract at an MTN shop. I logged this issue and was given MTN Reference numbers # ********** 5 and # ********** 88 with no one at Channel Queries acting on it for MTN or their agent. MTN, if you are reading this, please help resolve this matter quickly. I did not ask to be **** at an did not want to be in this situation. I just want an honest deal and contract. The agent that sold this to me must have done the same thing to other people and should be brought to book. My cell number is ********** 244.
