Unsatisfactory service

I've been with vodacom for nearly 20 years. On the 3rd November, I asked vodacom for a statement only to discover that there were 5 extra numbers attached to my account to the value of R2500 +. I phoned and spoke to a consultant who said she could not help me but she would send the query to a support specialist and gave me a reference number (1- ********** ********** ) and said they would respond in 7 working days. To this day, I have received no response in this regard. On the 30th November my debit order of R403 should have been deducted, but clever vodacom tried to debit my account with R66 735.03 which was luckily rejected due to insufficient funds. I phoned vodacom to query the debit order and once again the consultant could not help me. This time saying that the query would be sent to their solutions expert and giving me another reference number(1- ********** 113184) saying vodacom will come back to me in the next 5-7 working days. I was told that I don't need to pay my debit order as the correct amount will be deducted from my account once the query has been sorted. After contacting their accounts department I was informed that this is not the case and I would need to to draw the money and deposit into their account to avoid being disconnected. This is the shocking service I have received from vodacom and I fear that nothing will get resolved in the next month. I wander how long it will take to resolve this issue and whether I will receive another surprise at the end of December.
