Caller claiming to be from Canadian pharmacy trying to sell Viagra. They have lots of numbers and seldom use the same one twice. I've gotten hundreds of calls from them over the last 10 years. Screaming obscenities will stop them for a couple of months but nothing works over the long run short of changing your phone number.
Just another call from someone with a heavy foreign accent claiming to be Canadian Pharmacy. A Google search reveals that there are at least 6 websites responding to this name. I get calls from different "Canadian Pharmacy" scammers nearly every day.
