Useless

MTN an a network utterly ***********. I signed up for a data contract. for R959 they have debited me R1400 for the past two months and when I ask them how they got to that amount they ask me to present the contract that I signed. They can't provide me with my contract but it's okay to debit my account with that contract on their side but I can't dispute the amount without a contract on my side.
