Useless service

I have been waiting and calling autopage since sunday to assist me with a sim swap , none of these people have assisted me and in return i have lost about R300 in airtime just my calling their useless call centre,i have a contract with them and am paying every month,i expect a call TODAY! I am fed up with autopage and will stop my debit order if i am not helped because whats the use of having a contract that you cant use.
