I'm with Argos and don't have any complaints at all. They even paid out recently for something which I wasn't sure they would as it could have been seen as preventative. Dolly had a really large wart appear on her face, in the space of 2 weeks it grew to the size of a large brussel sprout. Vet said it wasn't anything nasty but advised removal in case it got caught and became infected.
Policy wording stated they wouldn't pay out on preventative treatments, but the cheque came through within a week.
They also paid out for my other girls xrays which I thought were excessive. Vet didn't ask if we were insured but she was booked in to have what we thought were a couple of xrays due to an intermitent limp on the front leg. Went to pick her up to be presented with a bill for over £700 (we were expecting c £250/£300), and to be told that they'd only charged us for 7 of the 9 Xrays so what was the problem.
Oh I think they're underwritten by AXA as well.
