Edgars RCS ripping inocent people off

I received a statement from Edgar's detailing that I owe them. Last time I checked my account balance was zero. Purchases were made on my account including cell C airtime (I use mtn and I use my bank app to buy airtime cash). I logged a complain using edgarsinquiries@rcsgroup. I then received and email advising that I will be contacted in 48 hours. It has now been a week and a half. I dont know how they calculate their hours. I am beyond annoyed by the way RCS treat customers. I must mention that on the statement it does not show where the purchases were made, it only reads 'Edgars SA'. Have you guys recruited *********. I dont want your lame apology but this mess sorted out ASAP
