Who is responsible through consumer law?
AM currently into 2nd year of contract through Virgin for a iphone6 plus. After the last update display was compromised with grey lines appearing periodically and becoming unresponsive. restarting would temporarily fix the problem, have tried all the others inc factory reset etc. Took it to Genius Bar at Apple who took it apart and said that the phone was in good shape, no sign of misuse Or damage. They said that for them to replace, as we didn't buy the phone from them, it would cost £229, but through consumer law, could cost us nothing, but it would have to be through point of sale, ie Virgin. Now just off phone to Virgin, first phone call went well, saying it could be repaired through consumer law and they would arrange it but suggested another fix. Fix didn't work and we phoned back only to be told that as it was out of year, had nothing to do with them and for Virgin to arrange repair via Apple would cost us £260. A manager promised to phone me back Monday. The question is, as this issue is not our fault, going down the consumer law route, who is responsible, Apple or Virgin as both are saying it's the other?
Many thanks
iPhone 6s Plus, iOS 9.3.1
