poor customer service

I settled an account in March 2021, I made the full payment towards my Homechoice account and received a paid up letter thereafter. Prior to this settlement my account was handed over to Capital Data because I could not afford to pay on the account at the time; I dealt with them to ensure that my account was closed and removed from my credit report and was assured it would be done. Only to find out that after the account was paid it was never removed from my name when I recently app**** for a bond. As a result of this my homeloan was declined due to adverse information and it shows the last time a paid was in February. I then contacted Homechoice again... and was told that i need to contact Capital Data. I called Capital Data and they referred me back to Homechoice saying that the account was listed at the Credit B by Homechoice and not Capital Data. At this point I was so exhausted and angry having to call them all the time. Meanwhile both companies were referring me to each other but not assisting me. Eventually i spoke to a lady at Homechoice and she asked for documents and proof that i have contacted them and that i have a paid up letter. She then instructed the credit B to remove the account from my name. Now I lost the opportunity for the house I wanted to buy, there are more houses on sale and i cant apply because i have to wait 3 months before i submit another application to the banks. All Homechoice said was sorry... they further damaged my credit record because the adverse information was not updated with the credit B, my credit score further dropped and all they had to say was sorry . I am so unhappy
