Professional Financial Services

I had a loan with professional finance service and I recently paid it off two months early in January 15th 2021 I was in the process of buying my house in march of 2021 they went on my credit and reported false information saying that I had late payments from August to December of 2020 than they went back up there saying I had another late payment in February of 2021 which was incorrect so by them putting that false info on my credit it has prevented me to close on my house that I am suppose to buy than I ask for a letter from them to state it was there fault and they will not prove I will not recommend anyone to get a loan with them they will not take responsibility for the mistake they caused in bringing my score down and prevent me from closing on my house I can't even get a loan at this point
