Unauthorized services added to Edgars account

I pay my husband's Edgars account and i have the secondary card. Imagine my horror to discover that there are amounts of R78 and R49 added for monthly payment for a service we know nothing about! Upon further investigation and lots of time on the phone to customer services we were told that it is for a cellular airtime. REALLY? We have contracts so why would we need airtime? Edgars customer services also said that WE have to sort it out and gave us a number to call - which never gets answered. When my husband then called Edgars customer services and eventually ended up speaking to the manager we were told that he would send an email to this RMCS that had added the service without permission and also copy us. That hasn't happened. We are VERY unhappy with this. Why should it be our problem to sort out the ********* practices on our account? EDGARS needs to come to the party and provide us with an answer and a solution.
