"Canadian Pharmacy" parasite scammers. I've told them at least 75 times to stop calling, now they get a police whistle blown in their ears. Hasn't stopped them yet, though. I'll block yet another number, but they won't stop.
This is a phone number for a pharmacy marketing service. SPAM! SPAM! SPAM! If you ask them to remove your number, they just hang up, then call again a few weeks later.
