Who called from 9018814493

Caller ID shows "Service Call" and no message is left.  I don't have any contact with anyone or company in Tennessee.  I've been getting a lot of similiar calls from others and have started not answering any call from any number I don't recognize.  The majority don't leave a message so I assume they're not important and are probably scams.

I got a call from this number and did not answer.  They did not leave a message.  I have no business with anyone in Tennessee ( I am in Texas).

I have been receiving calls from this number every week or so. No message. I know no one in Memphis, Tennessee.

Per "Spokeo", this number is flagged as a telemarketer...

This number calls at least 3 times a week.  Leaves no voice mail
