I've just left my current mobile phone provider (Vodafone) because of the continual problems with their website. Throughout the call to request my PAC (unlock) code every employee I spoke with didn't believe me when I said that I wanted to leave because of their site. I was offered increasingly more desperate financial 'offers' without acknowledgement of my actual complaint. Some big business' still don't relate web performance with user happiness - disappointing.
