********** by MTN

hi <br> <br> I had a contract with MTN from December 2012 to December 2014 which was suppose to be finish and I call them in December cancelling the contract which they said they don't have a proof of me cancelling the contract. then I received a call from lawyers representing MTN saying I owe 950 which I don't understand how. my belief was that after 24 months agreement they bill on month to month basis so if I did not pay them in January they continue sending me airtime until April even though it was clear to them i'm not paying. I thought if you not pay the line is suspended immediately. so I need an understanding of how come i'm owing 900 so far their lawyer have failed to explain to me. I also thought according to consumer Protection act of 2011 they supposed to call me or send me sms within 40 or 80 days informing of my contract. your help will be highly appreciated since I have exhausted everything at my disposal to sort this matter.<br> <br> regards <br> <br> B.H Sithole
