Robocall with female voice stating that my warranty is about to expire and inviting me to hold to speak with a "warranty specialist."  No mention of company name, type of warranty, product, or anything.  I hung up.  Almost certainly this is a scam.

I got a call on cell phone from Catonsville MD. Since I didn't recognize the number and don't know anyone dorm MD, I did not answer. Don't answer the phone if you do not know who the caller is  and put a block on the number!

Robocall, scam

Robot call went to voice mail 1/2 message on warranty
