Who called from 6013245142

Appears on caller ID as "Unknown".  Pest

Caller ID shows it's from McComb, MS. Called 6 times today between noon & 3pm. Tried to call it back once & reached a male's voice message that didn't identify himself (or company); just said "Thank you for calling, please leave your name & number...", so I just hung up.

Called at 4:58 a.m. and let it ring twice.  Says "Out of Area" even though I am in the 601 area code.

The 601-324-5142 number calls my number twice a day and NEVER leaves a message. How can I stop them from calling. Aggravating.

Caller was a political survey.  Phone associated with a Starkville, MS address.
