Hi, I bought a Samsung note 2 in july 2013. the screen was flicking and phone was freezing, then the screen didn't show anything. I took it to **** smith and they said take it to service centre. so did that. then they said it was liquid damage???? which is weird because its never been in water. so I went to the service centre to collect my phone cos I wanted to take it back to **** smith as they should have taken care of it as the supplier. took it back to **** smith - they said they can't do anything cos its liquid damage, and they suggested to get a second opinion. so took it to a technician and they said there is no way Samsung even looked at the phone and took it apart as the screws and everything are perfect - and there is no liquid damage from what he could see, the only thing it looked like was the screen needed replacing...... and now my phone has no signal with any network... so my question is what should I do??? take it back to **** smith to ask them to try and fix? or take it back to Samsung service centre? please help
