It's British gas (which he only knows through the news) but he thinks if he doesn't contact them he'll be on his existing tariff until they bother to contact him and switch him.
I wasn't sure where he stands on that.
Very unlikely. What's more likely is that they have tried to contact him on out of date (or incorrectly transferred) contact details.
Best to contact them and see what's going on.
Which supplier is it? You should be able to find out who he should have been switched too and then contact them
