Complaint Review: Reliable Credit

I purchased a car and financed it through Reliable Credit. I received a letter from them stating that my first payment was due September 10th and the 10th of every month there after. Now April rolls around and I have made a total of 6 payments to them ( I have the cashier's checks to prove it) and they are now trying to repo my car because I am 4 months late. Now lets do the math...... September, November, December, January, February, March, and now April. That's 7 months. How can you say that someone it 4 months behind on a car payment when they have 6 months of checks that Reliable Credit has cashed and the 7th month hasnt even been past yet? Stay away from them and run the other way!
