Telkom unable/incapable of dealing with a cancellation

I have cancelled my landline on the 23rd of October 2017 via email. I followed up about two weeks later and was informed that it takes Telkom 30 days to deal with cancellations. I went to the branch at Baywest Port Elizabeth and the consultant informed that he cancel my services unless the amount in arrears is being paid. I asked about my deposit and apparently that could not be used against the R 500 as it will only be paid out to me 90 days after cancellation was effective. On 30 November I phoned again and spoke with a a lady who gave me her personal email address: ********** and she promised to have the issue resolved. I have just received an account for R1500.00 which means that my account still has not been closed. I am being listed on ITC as arrears, being a bad payer which I am in fact NOT. Telkom is abusing my rights as a consumer and I intend on REPORTING THIS AT THE OMBUDSMAN if my query is NOT resolved within the next 3 working days. I have had it with inefficient call center agents and even more inefficient service.
