The number could be from anywhere in the world!  Yes, the 'computer Tech' guys really try hard to speak with an American accent and use a typical 'American' name. I've been called numerous times over the years and had played my own games with 'Alex'...who got very mad when I told him I would not turn my computer over to him.  I hung up when the swearing started. He called me back....twice.  Last time I said I'd called the FBI.or FTC. He hung up.  Two week after that, "Alex" called again. I reminded that I'd called the FBI, all my calls are now recorded.  It's been almost a year.  And so the scams start again with a new batch of idiots
