MTN - Lack of Customer Service

If i could honestly give MTN a zero star rating I would. They have been debiting my account since March 2018 for a Blackberry that I had years ago and is no longer in service. They then realized the error on their side after 3 months of arguing back and forth. To this day I have not yet been advised as to how they plan to credit my account for the amount of R4145.00 in total. I have received numerous numbers to advise that my account query has been escalated however this issue has still not been rectified, as promised I would log a compliant due to the pathetic service I have received, this is honestly the worst customer service I have ever received and quite frankly I am ready to cancel my contract with MTN . I would not suggest that anybody takes out a contract with MTN.
