I got a new contract with Vodafone and J3 mobile. The phone didn't get used much as I have another so it spent most of its time on the shelf. When it was a week old I picked it up and the screen had cracked. I have been messed about by Vodaphone for over a month now. They promise to sort it out for free. Tell me to take it back to the shop and the shop refuses to do it for free. Where can I go for help?
