Its a number for a "collection agency" called Dynamic Recovery Solution. They try to make you pay a "debt" that you "owe". Sometimes they are right about the debt and people automatically assume it is correct. Other times they call someone who doesn't have a debt what so ever. In my case, they called about adebt that my husband and I had already paid. They leave a callback number 866-625-8973. When you call you'll get someone then I got another phone number from the lady I said I would call back 866-637-7739. Don't fall for this. Look up the 866-625-8973 and you'll get tons of stories about these people.
