Expired contract

My mom's contract with MTN expired in March already, and I sent through an email to close it as the money is being debited from my bank account, she also tried to contact the 808 number but the number is forever busy and can't get through.<br> <br> I sent through an email on 24 Mar to cancel the contract and MTN responded on 05 May, asking if the number should be kept as pay as you, of which I rep**** and said yes. But no, MTN is still deducting money from my bank.<br> Can't they at least contact the customer as a service provider, just to check if the client would like to continue with the contract, instead of just chowing the money? I'm very upset right now so is my mother? she receive the data and SMS bundles which she doesn't even use.
