Walsh Western, to my knowledge.
When I googled them, because I'd never heard of them, I found a whole site of cases of their crapness. Speaking as a customer relations monkey, I'm horrified Dell don't offer compensation or goodwill gestures in cases like these...

You have a go at them hard enough, they will
It's like getting blood from a stone though.

I'm familiar with Walsh Western too - they're on my blacklist as a part of Lynx. I'm very picky as to who I use as a carrier at work - I'd rather pay more and not make the money than it not get there at all and have an unhappy customer. Who will then shout at me. I dislike being shouted at.
