Incorrect reporting of missed payments (Sept/OCt 2020) with no indication of willingness to correct

My Edgars account was taken over by RCS in 2020. During the takeover there were some serious issues and consequently RCS was under the impression that I still owe money on my account. After a two-month struggle RCS finally accepted that the account was paid off and that I was not in arrears. However, now my credit record reflect that I missed payments in September and October 2020 which adversely affects my credit record/score. I have twice (2x) contacted Waheeba Leonard and Patrick Davids regarding this issues with no resolution.
