Made small payment on outstanding debt, received summons for full amount today.
I have an outstanding debt with Capital One. The original amount was $2500, but now with interest and fees I owe $3500. Capital One has charged off the account and it was purchased by a local law firm. The law firm has contacted me several times asking me to pay more than I could afford, so in an attempt to get them to lay off I sent them a $25 check last Friday to which they responded with a receipt and letter asking me to have a payment in their office every 30 days. Today, which is one week later I received a summons for the full amount, court costs, attorney's fees and 6% interest of the pre and post-judgment.
Now that I have done some reading I believe that I just screwed myself by sending a payment to them in the first place. I'm not sure what to do from here. Everything I have read says to deny the debt until they can prove it is valid, but since I just made a payment is there any way to do that?
Just looking for some advice, I know absolutely nothing about law suits and don't have the extra money for a lawyer.
Thanks.
