Complaint against Edgars (RMCS)

Good Day

I have an account with Edgars where I'm receiving airtime which is billed from my account - it's a R55.00 Top up with RMCS. I contacted Edgars to cancel this contract but was referred to an agent known as RMCS, whom I have contacted numerous times with no luck. I was advised on the 13th December 2018 that this was cancelled but RMCS never advised MTN of the cancellation and for this reason I am unable to do a SIM Swap.

I'm sick and tired of calling their offices because I don't get any help and you hold on for 7 minutes at a time before call gets dropped. Edgars as well as MTN keep on referring me back to RMCS to get them to advice MTN that this "contract" was cancelled. I will stop paying my Edgars account until the matter is resolved as I took this out from Edgars and now a 3rd party is involved without my knowledge.
