Greek, why would they speak English? They're usually phone companies offering discounts.

In the US we get a fair amount of spam calls originating from India. So an english speaking country would be their target.

Hmm, I see. What are they selling?

I think mostly IT scams or falsely representing a tax agency. But these days I mostly get automated calls. I have a way around those which is when I answer a call, I don't speak until the other side says hello. Automated calls just assume the line is dead and hangup. I think these automated called are used by the spammers to identify live numbers a flurry of real call will follow up in a few days.

That sounds really annoying, I can't imagine being bothered by spam calls multiple times a week.
