I was evicted in July of 2013 I was told hat in order to stay where I lived at I had to come up with $2,500.00 or Part of it

Your chance to argue whether you owe money or should be evicted was when you were standing before the court in 2013 in the unlawful detainer proceeding. According to you, you owed at least $2500 but had only $2100. If those numbers are right, you did not have the money to pay all that you owed. The landlord was not required to accept partial payments. If you are claiming that you owe only $1,970.00 because that is the number on the credit report, you should realize that the numbers on credit reports are seldom accurate. To find out what you owe, you need to find the judgment in your case. The judgment will have the initial principal for the debt, the attorney's fees, the costs of the lawsuit, and the interest rates for the different parts. The interest rate is likely 12% annual and simple interest. You can review the specific facts with your attorney to find out your legal options.

You owe your landlord money and you wish to sue the company? If you owe rent, then pay it. The eviction order, according to you, stated 2 years ago that you had to go unless you paid. Seems to me that your facts and figures are the problem here.
