Collection Company suing me for 7000 in 10 days. What do I do?

I got a claim from one of a collection agency.. have 10 days to repsond.. what should I do. They say I will get a judgement against me.

also the original negative was reported and now that company tha tis suing me reported as well. so I have 2 differnet amounts because the claim amount includes fees.

what can I do ? I dont have the money to pay. orgiinal amount due to credit card 4600 all comes up to 7000 now with fees.

any ideas ?
