Consumer Portfolio Services Took car with tags and personal belongings and trying to make me pay more and not deducting correctly Phoenix, Arizona

Consumer Portfolio Services did deduct the money I was sending correctly because when you subtract $11, 055.73 from $280 the amount is not $11,055.73 and this is from October 2006 up until the came and got the car in November 2011.  They lied and said I sent $241 for a payment but I never did I always send $280.  

They are still calling me now trying to make me pay for a car that I do not have and the amount owed on the car is $3,376 but they want me to pay $3,907.51 but they failed to mention that the warranty money left on the car went to them and when you subtract $3,376 from $2,882.12 it is not $3,907.51.  They took the car to Hammond, LA and said they were selling the car but I have not gotten a letter or phone call stating was it sold or not.  I had to cancel my tags on the car and I had reported the car stolen because no one came and knocked on the door nor was I served papers.
