Dirty games

I have been with webafrica for long and their service has gone poor.lately the network give problems.i am not even sure if is it tht 50/25 i have signed for.Now my account hasnt been debited for consecutive months( march and april)when there is money in my account.instead of paying R629 i am paying R679 because of unpaid debit order which i am being ******. When i reach out to customer service it becomes a nightmare because it takes an agent about 5 hours to respond and when he or she responds she doesnt give reason why debit orders have failed.i have even tried to tell them tht i can sent proof of a bank statement to show that my account had money but till now they have avoided me.i dont want anything to do with webafrica.thy are ******
