Who called from 4249038986

I have received numerous calls from this number just today!!!  Each time I answer, they stay silent for a few seconds and then hang up.  I've tried to call the number back, but it doesn't ring...does absolutely nothing!!!

I have gotten 6 calls from this person with the same problem today

So they call us 10 times a day saying they are solar america. I told them to remove my number before but now i know they are a scam. I cant even call them back!

I receive many call from this number saying its solar america, a def. scam, and people they  are also a computer hack.

I have asked to be removed from their caller list and it never happens.  I continue to get calls.
