Who called from 5206865207

Received a phone call (multiple times).  Caller hangs up when you answer.

I keep getting harassing phone calls from 520-686-5207. The man wanted to sell me vehicle warranty extension.
Told him not interested but now he keeps calling throughout the day. Tried to call back and it was blocked.

I received a couple of calls form this number today.  I didn't answer, they didn't leave a voice mail.

2 phone calls from this number in the last 2 days.  I didn't answer and they left no message.

I keep getting calls from this number (a least once a day for last week) and the person never leaves a message.
