Who called from 4243491501

Multiple calls never any message or id. I am thinking of disconecting my phone to avoid these pain in the a** calls.

ID reads MEDICAL - DON'T ANSWER THE PHONE

I have received to many calls from this number some calls no caller id. The latest call id read contact  center no message,
reverse number lookup returned as  "non-existence"

Same as above…calls and does not leave a message. Hangs up as soon as the voice mail kicks in.

This number appeared as Compton CA, but when I checked a phone search website, the search result said "not a valid number."
