I'm also on 3 and have been for a few years now. Regarding customer service, the dealings I have had with them varies. online & social media has been good, the shops have been ok but they can be hit and miss over the phone! I've had some of the best customer service I've ever received with them and some of the worst!
The deal I'm on with them atm is an iphone 5 with 500 minutes, 5000 texts and unlimited data for £31pm
