Disgusting service from Support and Billing department

Its day 3 today without connection-I have sent several emails with proof of payment and support center agents cant even answer any questions i have called more than five times all they say we see that you are in arrears and that the matter has been escalated. I'm very disappointed because it shows that all weekend i will be without data. The payment was made on the 26th but still billing department has not yet updated the system. This is disgusting service I got and how do I keep on referring people if this is what we get if we do EFTs.
