I bought a Truck in XXXX and my score was XXXX and had been that for about a year. On XXXX XXXX my score went down XXXX points and on XXXX XXXX it went down another XXXX points and no one can explain why or have a good reason for the XXXX point drop. The service reps keep trying to sell me the monitoring program and it would not have helped at all. Why did my score drop so drasticly.
