I received a voicemail from this number today. The message says, "I have been retained by "Derby" and have documents to appear. I tried your place of residence and office. You have been officially notified and served". They said if I do not return call, a complaint about my business would be made. Of course, they do no leave the name of their company, their name or what in fact they are trying to achieve. They just lease a threatening message and demand a call back.
Just called and left a message trying to reach "Alicia Sanchez" for credit card purchases. It's easier just to block the number instead of calling back to fight them about it.
