The 3 mobile network amongst others are shocking, they have their "customer service" in a call centre in India, fcuking nightmare trying to have a "conversation" with some of these people.
Customer service in general in Ireland and the UK is appalling, im not sure about the rest of Europe though, in Dubai the customer service is of a very high standard much more so than anywhere ive ever been,they will go out of their way to help you whther than be in a bank,travel agent,shopping mall or airline reservartions.
