Stay away from RCS they're inconsiderate to clients

If your credit health matters to you stay away from RCS they're bad and their problem resolving manner is ridiculous... It's been half a year since I closed my account but still there's no feed back or whatsoever from them as to why they don't update my information on the ITC regarding my settled account with them... Instead of helping me they send me back and forth and ask me to email them the clearance letter everytime I make a query or follow up. It's 2020 what kind of tracking systems do they use that can't track payments? Even if you sent proof of payment and a settlement/clearance letter they still can't assist you with anything which is a messing up with our credit records... Useless, disrespectful, unprofessional and inconsiderate company I've ever known they have no respect for their clients or customers.
