MTN Data deals: A ****

MTN is the worst. I took a contract of 80 GB for R300 per month in February but I find myself paying more money every month for things that were not explained to me at the beginning. The person who was helping me get the contract, Hlayisani, is not even responding to my emails any more. The deal I took was R300 but I paid R600 in April, R800 May. I called to cancel my contract and they are saying I must pay R1000 .. I discourage all my friends and family to join MTN. This is more than poor service, its a ****. Our hard earned money!!
