It's a spammer. When I call back the number is disconnected.

This is supposedly from a pharmaceutical company. They claim to have sold me Cialis and Viagra in the past. This is a scam, and I have never bought anything from them. They keep calling every few days - despite my telling them repeatedly to take me off their list.When I call the number back, I get the "this number has been disconnected or is no longer in service" message.

Called my cell phone and left no message.

Call Type: Scam

Not just a scammer, but a thief.  They use spoofed numbers in the caller-ID which are not real, so you cannot really block them.  DO NOT do business with these people or give them any information at all.  The operators have a thick Mexican accent (Canadian - right?) and, if they know you're "on" to their scam, they'll curse you and hang up....only to call again some hours later. If you get really mad at them, they'll promise to remove your number, but that's just another lie.

SCAMMERS .... Do not answer !!!
