Complaint not resolved

Mutichoice has been doing as they please with my Account debiting wrong amounts without explanation and disconnecting me while they owe me R900.00.On the 28th August I was debited R900.00 instead of R319.00<br> i went and reversed it and I paid at Checkers.On the 28th September i was debited R900.83<br> again which I left since the lady that was assisting me told me account will be in credit once the issue has been resolved,nothing happened,Besides its effing up my credit.On the 28th October R319.00 was debited two days later I was disconnected they claimed That I have not paid.I went to their offices and was Assisted by a very helpful lady Ditshele Nembulunge she promised to sort my query out within two days and reconnected my account.She contacted me about the progress of my query and advised that she has elevated my claim to Accounts and is still awaiting response.This Morning I was again disconnected so I need to understand that why should it be my problem if they cant sort their things out I mean i have paid them overpaid even?.This if the worst kind of service ever its ******ion Iam disgusted with the level of service you give to your customer You guys dont know what y'all doin the
