Bad Service!

I do not understand why it is always a lonnnngggg process just to make a EFT payment if I have missed a debit order payment with you guys seriously. I follow the link I have been provided with to make a payment using the payfast option. I insert my number I have registered with when I first ordered Fibre with Webafrica, Then it tell me "Customer is not found for provider" of which does not make sense because not only does my bank have my cell number you guys do have my cell number as per my Customer Zone profile. Please assist me asap as I want to make a payment so that my internet can be up and running in the next hour!!!!! I have already chattered with Yolanda Mseleni of which is useless.
