When I answered nobody was there.

We too have been geting the calls.  Called our cell phone company & they have placed a blocker on our cell.  You might try that

this number calls me nonstop every day and has for about 4 months. They never say anything when I pick up, and then I found it it's international. I've done everything that I should. I've asked to be removed from the call list, and I left a message on their voicemail telling them to quit calling me. What are my next steps?

Oh my gosh I just received another call.  I did pick the phone up this time and explained to them that I already asked to be taken off their call list and if I receive another call from this company, that I was going to contact my lawyer.  Hopefully will not receive anymore calls.  If so I am going to pursue them.

I received calls from this number on my cell +4087963145, never leaves a message and so I called back and this is a grocery direct coupon call.  I asked for my number to be removed and as of this morning I received another call from them.  This is very frustrating

This number has called me weeks, multiple times, they know my first name but always hang up after I say hello?  I am tired of the phone calls and have already signed up for the "do not call" list.  I want this to stop.
