I received a call from a man named Mark Brown from French & French threatening legal action on 2 separate collections.  I've found several other posts saying this is a scam.  He directed me to call him back at 877-270-8211.  I don't know if this is legitimate or not.  He had a lot of my information which is pretty scary.  BBB has very little info on them.

These are the other posts I saw about them

A phone call, email or text message from a supposed debt collector is not legally sufficient evidence of debt.

The Fair Debt Collection Practices Act (FDCPA) includes statements such as this:

* Every collector must send you a written “validation notice” telling you how much money you owe within five days after they first contact you. This notice also must include the name of the creditor to whom you owe the money, and how to proceed if you don’t think you owe the money.   ["Written" means snailmailed ... not emailed or texted]

Therefore, if that caller wants you to pay immediately, before you get the written validation notice via snailmail, or if the caller wants payment via green dot, Western Union, or other untraceable means, then the call is definitely not legitimate.

IF you wish to communicate with the supposed collector / creditor, visit  the following page, for example "Action Letters" to snailmail:

If you KNOW you owe no money, or believe the call was from a fake debt collector, please take the time to read this:
