BAD SERVICE - VODACOM ACCOUNTS DEPARTMENT

I changed my debit order date timorously from 28 to the 1st and received confirmation. Only to receive an sms one week into the next month to say that my bill was in arrears and that if payment was not made within 3 days my service would be suspended. Numerous calls later they apology's for not submitting the debit order. I was assured that my service would not be suspended and that they would double bill me on the first of the following month. One week later my service was suspended on a Friday afternoon. I had to physical go in to the Vodacom shop and beg and plead for my service to be reinstated. This was eventually done even though all my arrangement details were noted on the system!! The next month they got the debit order correct. Just to get to 1 November and again they don't submit my debit order - once again we go through the whole process - there mistake no explanation given why. Confirm with them payment will be made by 26/11/2015 - get sms confirming payment received. Just to be double debited this month again. To be told by a very rude supervisor that they will refund me in 14 days. This is how they treat a client of more than 20 years.
