Who called from 4194687600

I haven't done business with these people and they called anyway.

Continues to call a school over 13 times a day.

This company is just calling businesses to update records claiming they are working on a project.

Some heavily accented man called saying his name was Martin and he was calling from the United States Postal Service.

Someone called the office saying they were from the Post Office asking for someone that doesn't work in the building. I told them that and then ended the call. Not 15min later, they called back saying they were from a different company asking for a completely different person. When told that someone just called from this number, they denied the accusation saying they were calling from a Skype number and that someone else must have used the account.
