This number calls incessantly. I usually just answer and hang up immediately. Someone on of these boards suggests buying an air horn (which I have)and when they call, set it off in their ear. It might not help but they probably won't be able to hear for a few hours.
Got a call from the same number but with a different area code earlier this week as well. This one though had a real person, but I couldn't understand what she was saying so I hung up.
Another "US Pharmacies" caller - they won't stop, even if you say you haven't gotten prescriptions from them in the past and aren't interested. Sheer harassment, plain and simple.
