BAD CUSTOMER SERVICE NON DELIVERANCE

Query with a revolving credit plan on my Edgars account. I have called on 3 occasions. They assisted me on the 2nd occasion , however my query was not resolved. I have always been a 6 month account payer since 1990's. Now that RCS has taken over EDGARS accounts they are doing an appalling job of it. They changed me to a 6 month REVOLVING CREDIT account holder @17.5%. Now excuse me who buys clothes at that finance charge??? I eventually got hold of a very sensible call centre agent, Nosipho on 12 May 2021 @4pm. She understood my query. Escalated it to complaints dept, who in turn will call me WITHIN 48HRS. It is now the 24th May, I am still waiting. THEY WANT THEIR MONTHLY ISNTALLMENT PAID ON TIME. Never available to assist an account problem. I would like that manager to call me and correct my account to a 6monthly account and therefore I should be done paying by June as my purchase was in Dec. I actually pay more than my installment as well. Really OVER PROMISE and UNDER DELIVER company
