Does anyone know Credit Protection Depot

I have a few outstanding PDLs I need to deal with. I had to close my accounts because all my paycheck was going to these loans and I wasn't able to pay rent or any other bills and I was in deep trouble.

Thanks to this site, I learned alot about these companies. I am going to deal with them on my time, but then I got an email from this company, Credit Protection Depot. I'm not sure which PDL they are representing or collecting for because it doesn't say. But they claim I owe over $800. Yeah right.

Anyway, I was going to write to them, but they leave no mailing address and there was this at the end of the email:

"Credit Protection Depot

**We are unable to respond to e-mail, please do not reply to this e-mail**

Unless you notify this office within 30 days after receiving this notice that you dispute the validity of the debt or any portion thereof, this office will assume the debt is valid."

Now, they are saying they can't respond to email, but I need to notify their office in 30 days. This is crazy.

Any information about this would really be helpful dealing with them. I don't want to deal with these people. I will only deal with the original PDL company.
