Bad service

I spoke to a retentions consultant in October after my 2 contracts had expired. I asked her to migrate the 2 contracts to pay as you to. She falsely advised me that there is a data contract at R199 per month for 20 gigs of data. I asked her more than twice whether I could cancel the contract anytime. She advised that with the data contracts, the contracts can be terminated anytime unlike with the normal contracts. so I opted for the data contract with an understanding that I can cancel them anytime . I went to the MTN store yesterday to cancel the data contracts and apply for normal contracts that come with cell phone. And I was told that the current data contract swill only expire in 2019 and there is nothing they can do about it. its clear the consultant was just interested in making a sale and did not care much about her customer's need, which is basic customer service . I don't even want to comment about the guy who was helping me in Sandton. MTN and poor service, its disgusting man...
