Yes I'm getting alot of calls from 312-340-5542. We really do not like being disturbed all the time about this. We consider it harrassment.

Eight calls just today. I keep telling them not ot call, but someone else just calls.

If you call the number back from caller ID you get a message to press 1 to be put on a do not call list. Don't know if that will stop it but worth a try.
You can also block the number depending on your carrier.

I called back and pressed 1, but keep getting calls.  Have filed a complaint with donotcall.gov.
