My story is long but with reading and is like many others who financed here... I did the end of year Toyota buyback in December 2016. My local Toyota paid the balance, 10 days later got the title and no long has the car. Now, the story - I sent 3 letters explaining above and they in April 2018, yup no typo sent the balance to a collection agency, added it to my credit report. I sent 3 emails a wk x 3 wks to explain above. Finally I called - they discovered what I wrote x 3 wks was CORRECT, they sent my account with the wrong files. They also marked me as deceased, yup dead...WHAT THE HECK? All they could say was sorry... My credit is tanked, one credit card closed, 3 credit limits have been reduced to current balance.. Oh, and my car insurance has gone up 30.00/month. I was trying to buy property which I cannot secure now because of credit score... They have ruined my credit and all they say is sorry? I have had Toyotas for 25-30 years but this will be my last. Oh, and yes I am very much alive... Want to hear the best? They sent the same stinkin letter yesterday, I owe the balance.... Enough said. All because people could not do their job!
