What a mess!

I have an account with Edgars/Edcon and was in credit of R1.15c not using the account. Since the statement from 07/06/2018 , I get charged for AIRTIME/DATA SUBSCRIPTION FEE R46-48 every month until now. After calling the account department to find out for what the charges/fees were, I was told to call another number to stop the subscriptions, after calling numerous times and being told that this will be credited, the charges keep continuing on my account, the call centre can't even give me a reason for what this charges is or who app**** or signed for this, being told that someone will call me back and explain everything to me.

Until date this is not sorted nor credited from my account, the account now at R145, I did not receive / subscribe or approve this on my account and did not receive any Airtime/data but this was added to my account. I am frustrated because my bill keeps increasing due to services I do not get or use. I want Edgars /Edcon to REVERSE all the money for the past three months. Also the interest charged due to this amount. Credit my account!!!! Why am I being ask to call a 3rd party that can't even answer any of my questions, who approve this service? Please sort this mess out!!!!!!!!!!!! What the hell who approved this and what is the service for?????
