On XX/XX/2015 I visited XXXX XXXX Used Car Dealers at XXXX XXXX XXXX, XXXX, XXXX XXXX with a pre-approved {$20000.00} check in hand to purchase a XXXX used Nissan Altima. The sales person ( XXXX ) asked if I wanted to cancel the {$20000.00} pre-approved check from my credit source and apply for a new {$20000.00} loan through XXXX XXXX for perhaps a better interest rate, My answer was no, " I do not ''. This queston and aswer was repeated 5 or more times with the same answer by both parties. I completed paper work to purchace the XXXX XXXX and a day later discovered XXXX XXXX had removed the warrenty and failed to dusclose the vehice had been in an accident. I also discovered XXXX XXXX had illegally slammed my credit report with an inquiry. This illegal inquirey was enough to cause EQUIFAX CREDIT BUREAU TO LOWER MY CREDIT SCORE. I filed a dispute with Equifax and XXXX XXXX and neither will process the dispute to remove the illegal inquiry on my credit report. I also sent written complaint toXXXX XXXX XXXX. XXXX XXXX XXXX, XXXX XXXX. My credit score remains lower than it was before XXXX XXXX illegally slammed my credit records. Can you please help?
