MTN please be competent

MTN has failed to debit for my contract in December &then they decided to suspend my line &I have made the payment on the 11th &still after that payment my line was suspended again &I made the 2nd payment again but still today my line has been suspended again..I have been emailing my proof of payments to their different service champions bt still no solution for my problem..How will I survive today without a phone..I have never asked for their contract they called &offered &I am not happy at all.I am very unpleased with their service.
