Palicades Collection LLC makes a false claim

SO I recently got a copy of my credit report. Everything on my report I could account for except for this account with Palicades Collection. I read someone else's question about this company and thought that perhaps since they're a repeat topic that someone might have some contact information for them. I am almost certain that this is a false claim... since this is the first I am hearing about them and I've never received any collection letters for the sum of money that is on the credit report. I'd like to try to get it taken care of so if anyone could help that'd be great. Thank you in advance.
