I received one of these type phone calls from a company who had recently purchased an antivirus company we are in contract with so they were sort of in startup phase. We were having major issues so I was happy they had called out of the blue promising to fix after I explained (we had no support contact info after the acquisition, old numbers were just cut off with zero notice to existing customers). After a month of emails, conference calls, and remote sessions we wound up back at square one with a product that does not work. The kicker: he tried to upsell us to their new SaaS antivirus after being unable to fix our problems! Then they stopped returning our calls/emails leaving us with a broken product we spent a lot of money on. Bottom line is I'm no better off for them having followed the advice given here. I think they didn't care and that initial phone call was only a sales call. Please never call me ever again, you are scum the same as pop up surveys on corporate websites. If I have a problem I will call you.
