Convergent Outsourcing, Inc. Fraudulent collection letter Renton Washington

I received a collection letter dated 07/07/2014. The letter was addressed to me but with an incorrect name that I never use. The letter stated that I owed $11,000 to a creditor. When I called the collection agency they did not want to give me the name of the company that they claimed I owe. They informed me that I was paying on this debt a few years back and I stopped paying. They provided me no information and expected me to pay. I have never owed any company this amount of money. This is a complete scam. I plan on filing a report with the Better Business Bureau and the consumer protection agency. If you receive a letter like this from Convergent be smart enough to not pay them a penny and do some research.
