Dynamic Recovery Solutions Outdated Credit and closed accounts being revived by ripoff company! Middle River, Maryland

I received a call from a company called Dynamic Recovery Solution. They are apparently a debt recovery company or so they claim. They tried to tell me I have an outstanding debt from Providian Bank for over $2000.00. First off I actually use to have a credit card with Providian bank about 12 years ago. I only had a $500.00 credit limit and the card was paid off and the bank no longer exists. This company is trying to get me to pay a debt that I do not owe and I don't even know how they have information on very old credit history! They are a scam company trying to collect on a debt that doesn't exist!
