Who called from 6615229408

I answered, which I never do with these robocallers. nobody replied. blocked...

Received call, unknown number and did not answer.

No answer ...no talking ..no message

Received call on unregistered google voice number. Robocaller left voicemail message stated that my vehicle warranty was about to expire.

Got a call from this number. Didn't answer and they didn't leave a message. Sounds like it is a scam from what others are reporting. Also got a call from (912) 549-7008 and others are reporting the same robo call about a car warranty expiring. My car is 11 years old, so the warranty expired long ago.
