Lack of service and poor customer service

Hi there I would like to lay a formal complaint on Webafricas service. I app**** in the beginning they advised me 5-7 days for install to my surprise 2 days later they called me for installation. They advised that i have to pay the router which I did. They asked me my preferable debit date is the 25th when I want it to go off to sort out one time . I was so happy with the service come month end they debit me on the 3rd not telling me their debits run in advance and not in arrears . Now they want immediate payment or my services will be suspended and I need this for work . I watsapped Malefa who advised the money if in their account my services will not be suspended . I asked them like the previous month now to make provisions because I am part of one of the biggest telecommunications company in SA I work for Daisy business solutions and we always make provisions for our clients because in this day we cannot afford to lose money and clients. Again I asked the lady can yourl make the debit for the 25th sure mam no problem. I get an sms this morning that my debit order bounced and if I don't make immediate payment services will be suspended . All well and good they can suspended but they will get not a cent out of me for no claw back usage and subscription because in the beginning they were so good their service has now become so pathetic.
