The Canadian Pharmacy calls me at least once a day from some number I've been unable to block. The current number is 903-650-9737 but there have been other numbers. They never leave a message but if you pick up they reverse connect you to a live operator in a manner that looks like they use an auto dialing computer with a database.

[***] called my cell phone.  I rejected the call and blocked.  They used to call my home phone but I now use *78 which hangs up on autodialers.  Eventually they stopped calling.  Calling my cell is [***].  Someone should kill these goddam drug pushers.

Got a call from them this afternoon and I answered but the audio quality (which was poor) along with the heavy accent of the person on the other end of the call made the it next to impossible to understand them.  I will be blocking this number.

the only thing I can determine is that this number is registered in Bayonne, NJ

If you get these calls on your cellphone install "calls blacklist" from the playstore. once they hang up press the calls blacklist icon and select the number from the recent calls list.

They kept calling trying to sell me Viagra before I started using blacklist (even after I had told them dozens of times to stop), so I started telling them: "Quit calling me, I don't need anymore, you're mother is too dry, your daughter is too young and your wife is too loose". They lose control and start calling you every name in the book in every language they know and it ruins their day, they probably don't sell anything for the rest of the day.
