heavy sales pitch for something or other, claimed to have dealt with me in the past about something (but didn't know what) and said I should buy products from him now.
Just now I received a call from 416 360 8879, lady says my computer has a virus. she wants my computer access. when I called back no dial tone, get disconnected. Looks like they want to steal my information.
I guess that this is someone from your friends who changed the phone company to WIND (They are just looking for new customers) and they taken his contacts and now blowing up to you. The representative office is located Toronto.
