MTN employees lie to customers to secure contracts

I upgraded my contract in July from a 20gb contract that i had, i was told the new deal was better and also expressed that i needed more data since 20gb was no longer enough, to my Suprise the new deal is also 20gb anytime data and the useless night data, i found this out since we have been having loadshedding and i use my small router a lot, so i was shocked that 60gb only lasts me a week and a half and only to find out i am still getting the lousy 20gb which i made clear was too little. i am very disgusted by MTN their customer service is horrible and they are just looking to make money and nothing more, i now want to cancel this stupid contract and i am told i will have to pay R3K for early cancellation, are they crazy? your consultants **** to me abput the data and now i must pay for their lies? i want the recording fro that day to be retrieved because i will not pay 3k to cancel a contract that was sold to me based on lies.
