Got a couple... never leave voicemails! Robocall?

Called it back, it's Sirius XM Radio Sales Calls

Ignored a call from this # yesterday. It left a blank voicemail which lasted 2s. I called it back and got the auto menu for Sirius radio. Sirius radio has called me from at least 4 different area code #s ( including this one, Also VA, DC, my local area code, and PA ) since I bought a "new" used car earlier this year. Over this time, I've already asked them at least twice to request they stop calling me, and they always politely say they will, but ultimately just blow me off. Annoying, borderline harassing with # of calls from multiple #s at all hours between 8 am to 8 pm.  SIRIUS-ly, f#%k you, Sirius radio. I'll never give you a penny, f#%k off!!!!

This number calls at least 5 times a day super annoying give up already. I dropped sirius radio because it was ridiculously priced. Thanks for the free trial but call me back when your prices are realistic.

They may be trying to use a loophole in the DNC rules.
Since you had a "previous business relationship" with them, they CAN call you back!
However, you still can report those calls to the DNC people if you told Sirius to stop calling.

If all else fails, consider buying a call blocker.
