I often wonder that myself.

I have recently been impressed by O2's customer service, some basic options (ie sales or technical) and you are straight through to a real life person who knows what they are doing. Brilliant.

Another thing that annoys me about delivery companies is that you need the tracking number, there are a few out there that only need your postcode and house number to find your package, why can't they all do that?

Cheers
