I purchased a vehicle from XXXX here in XXXX, Florida. I was made aware by XXXX XXXX XXXX they would start taking payments on behalf of XXXX  beginning in XX/XX/XXXX. I asked for documentation showing they will subservice my loan as of today I have not received any documentations. I also asked for documentation showing the loan amount which was n't correct as well. My loan payment is due the XXXX of every month I normally paid my loan towards the end of the month. After receiving emails from one of the representative I advised that I normally pay before the loan before it becomes delinquent. The XX/XX/XXXX payment was paid on XX/XX/XXXX which is 29 days after my due date. I received an email from representative advising my loan was in default because I did not pay the late fee. I responded back advising I should not have a delinquent payment because the late fee was not paid. I also noted that this should not be reported on my credit report as I was in the middle of trying to obtain a lower interest rate from my mortgage company and I paid the amount in my contract which was XXXX. I did not receive a response. Towards XX/XX/XXXX, I applied for a refinance for my home loan. It was discovered that XXXX reported me 31-60 days late on my credit report in XX/XX/XXXX. I called and was told they report the XXXX of every month and if the payments are not paid in full then its reported late to the credit bureau. I advised this is against the Fair Reporting Act.15 U.S.C. 1681. And they are violating 623 section 3 and 8. I was told to send an email with my concerns to the email box " contact us '' on their home page. I sent an email and did not hear anything back from them. I called on XX/XX/XXXX, regarding the late payment reports. The supervisor advised me that they have a right to report late payments if the payments are not paid by XX/XX/XXXX because they report on XX/XX/XXXX. I explained my payments are due on the XXXX of every month and I have never paid 31 days late. I asked for a copy of my loan agreement and he said it did n't matter because they purchased the loan. I advised purchasing the loan does n't change any terms. I asked for the contract showing my signature that changed the terms of my loan. He advised to dispute with credit agency. I asked for the CEO or Owner to write a letter and he would only give me a first name and a partial address. I asked for their business license information to operate in the state of Florida and he would n't provide. I advised this is violating my rights to dispute inaccurate information and they are willing and knowing reporting incorrectly. He would n't address the my concerns and advised to write in. I tried looking this company up on the business license website and shows their business license for XXXX XXXX XXXX XXXX, License type, Consumer Collection Agency, was withdrawn. I contacted our State Business office and was advised XXXX XXXX XXXX does n't have a license for Florida. She located a company with a similar name which was a dealers license, no license to auto servicing loans. I was able to refinance my home loan however this late caused my credit score to drop and thus caused my interest rate to be higher than it should have been. This issue has caused un-needed stress trying to correct this incorrect reporting. I am able to refinance again in 6 months however this need to be corrected.
