First Investors Financial Services Takes your money but does't put it on your account Internet

I paid my vehicle off some years ago and never received a title. When I call about it they said they had not received my last year of payments. I provided all my money order receipts via fax. I then checked the first money order from the date the said they stopped receiving payments and the last one I sent. First Investors Financial Services had cashed them. They then stopped answering my calls by placing me on whole for long periods of time. They took my name and number and would never return my calls. Other days they just hang up in my face. I have not title to this day and its been over several years. They have not come to repo my vehicle but stated that I owed them money. I now have this on my credit report and cannot register my vehicle in the state where I have relocated too. They have a BBB status "A+" posted on their website which has to be an out right lie. The need to be stopped.
