MISLEADING TELEPHONE SALES!!!

I was on the black Friday deal which i received in November 2016. This contract lapsed in 2018 and i did not renew my contract. In January this year, i received a call from Ernest from the KZN contact center, regarding a data only deal. He advised me that I was free to cancel the contract at any time and that no penalty was to be charged for the cancellation on this deal. I called the MTN contact centre last week, only to be notified that i signed a 2 year contract and i will have to pay cancellation fees if i am to terminate my contract early. This is ridiculous, and i feel misled, cheated and mistreated by a Company that i have dealt with for almost 5 years. Why did they have to lie to close a sale and why do i have to pay a penalty to cancel when it was expressly made clear to me that i could cancel at any time that i wanted to. On Friday, i spoke to Ernest, who advised that he was escalating the matter and that i would have feedback by Monday. Its Wednesday, and nothing has been done as yet!
