Just got a call from them and they tried selling me VIAGRA wow no need fpr that

I just got a cal from this # (519) 570-4223 I answered and nobody said nothing.
Have had them  before too.

Called one of my home phone last year November. Went to voicemail but didn't leave any message.

Called my cell phone this year. Went to voicemail and still didn't leave any message.

I called back the number and after two rings the automated message said ""We're sorry the number you have reached is not in service...."

Called me when i was sleeping off a night shift. Around 10 am that is. I guess i must have answered. But i dont think anyone was there. Got 3 calls in around 30 mins this was the last one. One was a blocked number and the other was another 570 number. I was worried i had hung up on a potential boss. But good to see it doesnt look like it.

Got this today at noon.  Guy on the line asked if I was the person who used a computer in the house (yes) and informed me that my computer was "sending out infections".  Ha!  I assume I was to be asked for all sorts of personal information (including credit card or remote access to my computer) but I laughed, said "Not it's not - what a scam!", and hung up.Will be reported.

Keep getting calls from this number, same time each day. I can't understand who they are asking for and ask for a message and they hang up. When I try to call back the number is not in service. I get the same result when I do a reverse lookup.
