I got a call from this number yesterday. They identified themselves as benchmark. They called me regarding an old credit card debt. The woman I spoke to was polite and seems nice. I have asked for proof of the debt they are collecting and she has agreed to send it. I haven't received it as of yet, but if it all checks out, I will make arrangements to take care of this. My experience with them has been ok so far. I think they might be a little surprised that I am so willing to take care of my debt. Anyway I can't really complain. I owe a debt and they have been retained to collect it.
