RMCS & Edgars - Unauthorised Deductions on my Account

RMCS, through Edgars, have billed me R25 for SMS Air susbscription on 19/01 and 01/02 on my Edgars account. I did not authorise this at all. In fact, when I called in to request a refund and a cancellation on the 13th February, it was established that this "airtime" was going to my old mobile number. I was given a ref ********** 444709. A few days later I called to follow up and was advised that the subscription had been cancelled. No mention of a refund. A request for refund was only submitted by the agent on 21/02. On 26/02 and 05/03 I called to follow up as I had heard nothing from this company. I was advised yesterday by Keneilwe that according to the system someone had tried to call me on 04/03 (a Sunday of all days??!!) to verify a few things. Not one missed call on my phone from Sunday. I then gave her my work number and asked that they call on that number if they couldn't get through on my cell. At this moment (8h42 on 06/03) I have still not heard from them. Calling them is a nightmare - you can wait up till half an hour before someone actually answers. All of this just to get R50 refunded to me!!!?? I personally think Edgars need to re-think their alignment with this company because they seem to be completely ********* in the dealings.
