On air and MBD is a ****!!!

Worst service. I've requested a statement from MBD they cannot provide me with a statement. I asked them my outstanding balance they could not provide me with that either. I went on their website and I settled my account they came back saying I owe now R480 again I paid it immediately. I requested a paid up letter they now telling me I owe R18 I requested a statement they say it was sent to me before I asked them to resend it the lady dropped the call in my ear. It shows on my account there is no statement so the balance. they just want more money amd this is affecting my credit score hence I settled this account that I did not even sign up for. On air **** and said they from DSTV in the meantime is an outsourcing company that's eating people's money.
