I got an auto loan from GM Financial, began paying in XX/XX/XXXX. SKY high interest rate of 14.27 %. First lie : GM said after one year they'd renegotiate to a lower rate. That was a BOLD FACED lie! They switched gears and claimed " oh we don't do that ''. Then I paid payments and over time I realized they were NOT applying the payments correctly. I asked for an exact accounting of principal vs. interest, GM Financial refused to provide that. I have, over time, due to health issues with my wife, a XXXX XXXX survivor and now complicated XXXX/XXXX had several extensions. Each time I was charged fees, but you can not find anywhere where the fees are applied. I asked, GM Financial refused to respond. Then GM Financial agreed to a two month extension, said paperwork was on the way, but reversed course and did nothing. I have asked about lowering the interest rate as promised, they refused. I have paid, before the XX/XX/XXXX payment, XXXX towards the original loan of XXXX. Of that according to the paperwork XXXX was/is interest, BUT they have charged me XXXX interest. I have been CHEATED out of XXXX. When I asked about this they claimed they could not answer that. GM Financial is running a dishonest operation that scams customers.They stonewall, refuse to show payment breakdowns of payments, refuse to lower interest rates, refuse to give you any explanation of questions. They have fuzzy accounting that is worse than loan sharks.
