MTN - No Service - NO SERVICE

I have been a loyal MTN Customer for 25 years and I have never had a bad experience - until now. In July this year I app**** for Home Wi-fi - paid the pro-rata portion and the month in advance fee. No issues. End August - not knowing a Debit Order will be deducted - I made a manual payment towards the account. A few days later - a Debit order was processed. I phoned in to find out why this was done only to find out - the payment I made went towards the wrong billing account. I requested a journal to be processed to transfer th emoney to the correct billing account. I then reversed the debit order. The so-called service champion was utterly rude and when I insisted to speak to a superviso rather- I was told the supervisor was busy. I asked if I could be called back - this never happened. On Saturday 04/10 - my service was disconnected. When I phoned in I was informed the account was not paid. I advised that a month ago i requested the account to be rectified and was informed that a new request will have to be logged. When I queried how long this would take - I was told 24-48 hours but my service will only be restored in the new month. This is unacceptable. I paid the account on time even though this went into the wrong account - but called to have it fixed in time. If an agent does not do their work - then why am I penalized? Another Debit order was processed on Saturday - so 2 payments were received for this account - yet I must wait a month. Unacceptable. I expect the account to be rectified and services restored with immediate effect
