Mtn uselessness

As many other reviews about mtn keep taking money after you try to cancel a contract that has expired, and they just dint respond and cancel as requested. I have same problem with mtn... so I had to cancel debit order at bank. Now they handed over to recovery agents. I GOT ALL THE PROVE OF EMAILS SEND TO CANCEL. MTN. What a ****ty useless service provider. I wont support you again......never. your cellular service also bad
