Rotten service

I have never had such bad service from three companies that are supposed to be working together. I paid Edgar's finish in December but did not know I overpaid the account with R550. I found out that I overpaid when I checked my credit score on Clearscore. I then went into a Edgar's branch to have them refund me for the overpaid amount. They took my bank details and everything to log the call with RCS who has taken over Edgar's apparently. They told me it would take 22 days for the matter to be resolved which did not happen. I then phone RSC customer service who had not been in contact with me since the call was logged for me to be refunded back "my" money. They then told me after waiting 27 days that there is nothing they can do for me and that I should phone Consumer Friend and that they must sort out my refund. I then spoke to Siyabonga at Consumer Friend that said he would sort out the matter and that I should not worry. When I phoned Consumer Friend today and asked for Siyabonga this female consultant told me they only take in coming calls and that they could not phone out so I can't speak to Siyabonga that assured me he would sort out the matter. She then said to me sarcastically that Edgar's / RCS did not send them the proof that I overpaid and that I must phone them to do so. She told me I am gonna wait a month to get my money. I then phone Edgar's customer service back and was helped by Chanell that said that they could have gon in the system and saw that I overpaid. She then sent Consumer Friend the details of the overpaid amount and said they would sms me. I mean if I had owed them they would harras me for their money but it's mo ey they owe me. I will never do business with, RCS, Edgar's or Consumer Friend ever again and I hope other people also won't because i have had other people also complain of RSC but never experienced it until now. All I want is my money back so I can close my Edgar's account.
