All our corporate clients are dealt with at our head office so we do not actually see any of them.

Correct entry: them
The error was: (c) they

Could I also use the preposition in? I mean Could I say: All our corporate clients are dealt with in our head office?

Thanks a lot

The use of 'in' would also work here. It would suggest more precisely that this took place inside the head office.
