Our Monthly billing rate is {$630.00} and I have been trying to get Hyundai Motor Finance to fix inaccurate billing issue for months, since XXXX of XXXX and still have not gotten anywhere. After disputing inaccurate charges on XXXX 3 times Hyundai account information still was not changed to an accurate balance. So after nothing has changed I decided to contact CFPB around XXXX or XXXX and the response they received from Hyundai was that amounts were correct when they absolutely were not. After receiving XXXX, XXXX, XXXX, and XXXX billing statements we were still being billed to me with not only inaccurate charges but inaccurately reporting days of past due amounts to the credit bureau. I then decided to contact the XXXX on XX/XX/XXXX to see if I can get some real help that way. On XX/XX/XXXX I get a phone call from Hyundai Motor Finance executive office because of my XXXX complaint and I spoke with a person by the name of XXXX XXXX, After telling XXXX XXXX about my reason for contacting the XXXX, XXXX assured me and the other person on this account who also was on the call and is the co-signer of this account that he would be fixing the inaccurate charges. He stated that we would probably be on the line for at least 1 hour to try and fix the issue. So as we were going over the account with XXXX XXXX he stated that he thinks he has found one of the issue which was that to him it looks like our payments or not reflecting. After looking at the account some more he stated that it looks like they put or repo fee of {$2300.00} that me and my husband already paid in XXXX which had to be a {$0.00} balance, was added back to our account, which he didnt know for sure. He kept saying he think he sees were things went wrong at on their end. He also said that what he can tell so far from looking at account is that the billing should not be as high as it was but again thats because of all the inaccurate charges they kept adding. And also when you go into your Hyundai Motor Finance account it says you are 90 days past due which was also inaccurate.Towards the end of the call XXXX XXXX also stated that he was putting the repossession they had outs for our car on hold because of the inaccurate charges then XXXX XXXX stated that he would reach back out to us by Friday XX/XX/XXXX and if we didnt hear from him to give him a call. So me and co- signer contacted XXXX XXXX XXXX XX/XX/XXXX to see what progress has been made in fixing our account and he stated he was still waiting to hear back from whoever he needed to look into errors. But on credit report it states that account was closed on XX/XX/XXXX so why didnt XXXX XXXX let me know that my account has not been fixed but reported to credit bureau as closed and charged off. Me and co-signer tried contacting XXXX XXXX Directly again on XX/XX/XXXX over 11times after getting notification from my XXXX account showing that my Hyundai Motor Finance Account had been closed and Charged off as bad dept when they were supposed to be fixing the problem, and still no answer or response from Mr.Bishop. XX/XX/XXXX me and XXXX tried contacting XXXX again after getting notification after getting notification from XXXX again now stating that account was charged off ( 9 ). As Im writing this on XX/XX/XXXX now Im am trying to contact XXXX XXXX I called 10 times back to back and I didnt get an answer, or a response after leaving voicemails on XX/XX/XXXX and XX/XX/XXXX. I am asking that this situation is thoroughly looked into now after being lied to by XXXX XXXX from the Hyundai Motor Finance Executive office, who is now ducking phone calls, emails and clearing our calls when he was supposed to be straightening out the issue. And why are theses write offs and remarks to credit bureau changing so much and negatively instead of taking time out to fix mistakes.
