Qchex ripoff San Diego California

I received three checks from Qchex mailed from San Diego, California. Today I was told by my bank that the first check was fraudulent. How can they issue checks without verifying with the customer first. When I emailed Qchex, they seemed unconcerned and I was told to contact the customer. Isn't that what they are supposed to verify before they issure the check? Is Qchex involved in a money laundering scheme?

I am sure it is just a matter of time before the other two checks come back returned to me.

Do not accept any checks issued by Qchex from San Diego!
