Who called from 2028034978

Just received a call from this number as well. I let it ring and go to voicemail. No message left.

Just received a call from this number and they also didn't leave a voicemail.

Same here, no one is talking.

Received a call 2 mins ago to my business ext. - was a recording stating 'their records indicate my vehicle warranty has expired'. I'm not even located in the USA.

I believe these may be some kind of scam artist if they are talking about vehicle warranties expiring. I got a missed call on my cell from the same number but I let it go to voice mail. They left no message.
