Edgars taking airtime subscription fees that I did not sign up for

Since August 2018 I have been receiving an airtime subscription and a sms bundle on my statements that I did not activate. On the 6th September I went to visit their Westgate store and asked them to cancel and reverse the transaction. U was given a Reference number and promised that it will be done and I will receive a call from a company called RMCS to confirm the cancellation. On the 13th September 2018 I received an electronic statement Edgars where now my account was debited twice for the airtime subscription and a sms bundle I then went back to the store to lodge a complaint again and ask them to please resolve this immediately. They then called RMCS again which now told me the transaction gets resolved within seven days.

Today on the 17th September 2018 I went to check if something was done then i was told not yet. They called RMCS again and they responded that they tried to all e and I didn't answer and the matter will be marked as urgent. I asked the customer service agent that I only have an agreement wit Edgars and how an the give my account details to a third party, I then demanded to ask to talk to the store manager and I waited for more than half and hour until i decided to leave the store.

I would like to be helped since I am not prepare to pay for something that I dd not sign up for
