This number belongs to WCA Subscriber Services. They called me with a recorded message to learn more about diabietes. Any recorded/automated calls can be reported to the donotcall.gov even if you are not registered. Also 520 area code is in Arizona. Arizona makes automated/recorded calls illegal as a Class 2 Misdemeanor under ARS 13-2919. Report them and stop annoying telemarketers!
I got a call this AM from this 520-254-6287 and it's not the first time. I remembered something from an email I received about how to get rid of telemarketers and that was to answer the phone and hit the # symbol as fast and as many times as you can. I did this, then called the number back. I got a recorded message that said something like "your subscription has been cancelled and your number removed from our data base." You might want to try this yourself. I hope it works.
