Contract cancellation

I have had a very unpleasant experience with the MTN team , I have had two LTE contracts and I have never missed a payment , now cancelling my first lte contract was a struggle I had to call in repeatedly and eventually came right , now my other contract has ended last year October and I have called in today , to be told they cannot cancel a home plan over the phone I need to go into store , from my last experience when you go into store you are told to call customer care , they are unprofessional and waste a persons time , I will not recommend service provider to anyone, also a debit order went up from R1050 to R 1468 per month
