We have received a few calls and this time - left a message of heavy breathing around 8:10pm.  I did call back, left a pissy message and tomorrow - we will be blocking these calls.  
Annoying.

This is a business please stop calling and hanging up when answered, or leave a message

I received the same call earlier today and no one left a voicemail. I then called it back and it was a generic message saying it was a call center,and if you want to know who call from this number then leave your info..ha! What type of business are your running?

Keep getting calls, no msg left, sounds like heavy breathing on other side

I got a call from them today and they said they distribute free grocery coupons from the Sunday paper every week. I didn't ask what company their from because I wasn't interested in giving my address. I looked up the number to see if they are from a newspaper or legit distribution company...but haven't found anything.

Yesterday, we had ten calls from this number; the day before seven and, today, one so far.  We have it blocked so our phone only rings once and then hangs up with calls from this number.  We are tired of this nuisance.

5 to 10 calls a day past couple of weeks. when answered no one on line never leaves a message.
Can I pursue this legally?

This caller keeps calling me on my work number.  The caller will not leave a message on my voicemail.

I keep getting a call from this number.  The caller won't leave a message when I don't asnwer and when I forward it directly to my voicemail.

Called twice every night

Called office, no one answered on the line.
