Vodafone are the worse company I have ever used for a contract phone. Since January, every month they are telling me that I am using 30gb minimum per month on data which is very untrue, after going into the store and also going into Apple they have confirmed it was not me. I have a bill for £260 due to this! After one guy on the phone apparently cancelling my contract I called back to check and there was no record of this conversation. If you have a complaint you won't receive a call back!! I have called Vodafone 2/3 times a week since January and still no resolution.. DO NOT USE THIS COMPANY!
