cancel contracts & refund for wrong debits

I had contracts for *** &amp; *** which I cancelled on 15/11/2015 &amp; 15/12/2015, respectively after I was advised by a consultant to first used the airtime which I would forfeit on the latter cell phone number. The 073 number was, on my instruction, already suspended before I cancelled the contract and therefore it did not any balance owed by me and it was confirmed so before termination. <br> My account was debited on 15/01/15 &amp; 15/02/16 for R 850.70 and R 815,75, respectively. I called on 28/01/16, 10/02/16, 15/02/16 and 16/02/16 (ref ***, ***, *** & *** respectively) to complain about it and spoke to numerous consultants who promised to attend to the matter, but nothing came out of it even though I had indicated that my other debit orders would bounce as a result of insufficient funds.<br> Can you please help me recoup my money speedily in order to service my other financial commitments and stop mtn from further debiting my account<br> Andrew, ***/***, email: ***
