Who called from 7815460013

Called company cell left no message. Blocked the number

Called my cell phone which I don't use as a phone.I use it to text a few friends. I didn't answer. No one calls me on this. I use a landline.

They call my phone every day but never leave a msg. Putting on my block list.

Called my cell phone.

Didn't answer. However, if it's about a car warranty, it's clearly a scam. I have no car; don't even drive.
