Progressive Debt Relief

My husband and I have some store front and online payday loans. A collection agency had contacted my husband in regards to one of his online payday loan to set up a payment arrangement with him to get it taken care of. My husband agreed and gave them his check card information, and how much he wanted to be taken out and when. He was told that he would receive documents in his email regarding the arrangemts, he hasn't received anything. He was contacted by Progressive Debt Relief and was told that one of their other clients had done the same thing, and that the collection agency decided to just pull out the whole amount instead of following the payment arrangement. My husband has decided to go through this company, because I am guessing that it would be cheaper and we won't have to worry about getting lied to and never getting a contract confirming the arrangements. Before we set this up, does anyone know anything about Progressive Debt Relief and if we should use them?

Thanks
