Bad service

We never had problems with Rain, the last 5 months is irritable & annoying to say the least. You top up with airtime to your phone, because we use rain sim cards, they take 3 days to allocate airtime that you need now to use for business. Nevertheless, our payment date by DEBIT order is set to the 1ste of every month, by the 16-18th of the current month, the cut services because they say we need to pay our account. So, if my debit order went off on the 31st of Aug (which is not the 1st) & today is the 16th, why is my service cut AGAIN?? It takes us every month to phone the call centre (A whole lot of 4 - 6 phone calls, check your records) to ask them what the hell is going on? Why do we struggle with Rain, your service is really questionable at this stage.
