Same as above. Got a call during dinner, rejected it, no voicemail left.

Called, rang until voice mail pickup but they left no msg. - I called back, it is for a telephone survey.

Automated female voice saying "this is your final notice that your warranty is about to expire". Warranty on what?  Automated voice does not respond to questions. I hung up.

Thanks for the info

I happened to have the phone in my hand when a call came in from 720-214-1765, with the ID name Fiebig Joseph W.
This data is highly likely to be fake since the woman on the other end said she "This is the warranty department calling
about your expired warranty".  Boooogussss...
I replied I wasn't interested and she responded with, "Oh well.  You have ignored our final warning.  We may have to delete
you from our database".  I replied "Great, so now you will stop calling", and hung up.  This was a live (but brain dead)
person on the phone, not a recording.  Probably some poor person caught in a work-from-home scam, so I won't be too
hard on them.
