Serves you right for switching and not keeping a stable record!

These were each over a period of a couple of years, so there was a
pattern.

I meant your record with the suppliers:-)

Well.... if I hadn't found this overpayment practice happening
consistently, I wouldn't have bothered to make an issue of it.
However, the amounts were quite large and no offer of interest on the
amounts was made. Therefore, I think that it's perfectly reasonable
in a subsequent year to underpay them for a period in order to recover
the lost interest. Taken over a period of a couple of years it works
out evens.

Perhaps the companies work on the same basis!
