I recently bought a NEXUS 5 unlocked phone at a local electronic store. After 3 month I started experiencing issues with the screen. I went back to the store and was told I have to contact LG since the store doesn't provide warranty. So I called LG, after they looked up the serial number they told me that this phone is a model from the UK and does not have any warranty in the US.
The store I bought it from is refusing to help me in any way. Is there any legal action I can take? Is the store allowed to sell products not intended for the US market and has no warranty?
any advise would be greatly appreciated.
