COMMONWEALTH FINANCE Collection Agency Scam Dickson City, Pennsylvania

What a week! After years of working to successfully improve my credit score I have had the wind knocked out of me by a company called Commonwealth Financial Systems, INC of Dickerson, PA. This collection agency has listed three separate accounts in collection on my credit report in just three days. I was shocked when the first account appeared. I have absolutely no prior knowledge of this account and immediately filled a dispute.  Only to be notified the following day by my credit monitoring company that the very same company had list two more accounts for separate amounts as delinquent and in collections. I am so disheartened after working so hard to be responsible with credit only to have a company like this come along and try to bully me into paying them for fake debits. Any advice would be greatly appreciated.
