Personally, I haven't had much luck with my dealings with Orange's uk customer services, but it's still infinitely better than having foreign callcentres. I think T-Mobile are making a huge mistake outsourcing, they really should learn from other companies that have withdrawn from India and the likes, and keep their uk based staff.
Obviously it's a cost cutting exercise, and I shudder to think what their service levels will be like in the coming year. They're obviously more interested in their shareholders than their customers. Still, we'll see soon enough.
