*****ulency on edgars account

I have a account at edgars and i had a problem where the third party is charging me for mobile data content which i did not sign up for they said that i have activated this on my cellphone via a link. I did not activate this this service as i have a contract sim and it does not allow me to receive any data as from any other source. I have contacted edgars on numerous occassions quering the account but nothing has been done till date. I also contacted edgars 3rd party who is charging me for this mobile content data. They are rejecting me saying that i have activated this account via a link. I asked them to provide me with a proof of activation for the link and also a voice message were they told me that before they charge me they gave me c all to get my consent. They failed to provide me with this information. The lady that i spoke to at rmc was wandile and the ref they gave me was ***. Uptil now the problem is not solved. My Edgars account is in arrears now and im being charged a lot of interest due to the fact that edgars refuses to pass me a credit of R550.00. Who is no going to be held responsible for the account being in arreas as this account is not being resolved by edgars. I would like hellopeter on my behalf to assist and solve my problem.
