Complaint Review: CBS collections

I was billed for a apartment move out. My roommate and I were both billed the same amount. My parents and my roomates parents were also filed against. Both of our parents settled the claim. Then 3 years later they came to me and filed another judgement against me for the same claim. I produce the paperwork of the settled claim and they continued with the judgement against me. I had my check garnished,and I was never served. I have paid the claim and I have turned it over to a lawyer. I was told by the lawyer it will take up to 3 years to get my money back. They are ruthless and have no legal sense. They will stop at nothing to continue to keep getting money and ruin your credit. They do NOT follow the law and when the judgement comes it is to late as you never even knew it was filed. You are noy given notice to respond. They falsely claim that you were served.
