Would you ever expect a legitimate call from your bank / government / business to be in English? Particularly English with a strong Indian accent?

I think the US gets targeted mostly because of language. Indians learn English in school and it's not uncommon for a legitimate call in the US to come from someone with a strong accent.

A couple of items to our advantage: there are quite a few carriers here but only very few of those have physical infrastructure and those tend to have strong political connections. They are tied in with LE and AIVD at the operations level and have excellent security departments and a reputation to uphold. Then there is the willingness of the local authorities to put time into this, and publicize when they nab some of these scammers. And finally, NL is a small market with a weird little language that isn't spoken much outside of our borders. (South African doesn't count ;) ).
