CA summons to court.

I need some assistance on dealing with a CA Kramer Frank. They acquired my account in late Aug08. I sent a Debt Validation letter to determine that they had the account. The forwarded the account info from Ford. But the outstanding balance was inaccurate. I called them several times. Sent emails (have records of all) They would not call and sent no further statements after Sept08. In Jan09 received the summons to court. While in court I explained to the judge that I was never give the accurate outstanding balance until I received the summons. That the stop all communication. He stated that Kramer need to handle my concerns before coming to court. The attorney informed me that I could step outside and make arrangements with one of the collection represenatives. She was clueless and no help. We are talking about a total discrepancy of $950. $480 still questionable. What legal steps can I take. Will this summons appear on my credit report? I am will to pay what I owe but what they reported to me was inaccurate.
