Bought a phone (AP- SE w980) used around 3 months then LCD have black dots.

i sent back the faulty phone to the shop and get service, after 6 weeks they said it's not under warranty because they accuse i broke it myself. They told me i must accept what they telling me and no warranty given. lol

After reading this thread, seems like AP and ORI also same. They will always do their best to avoid warranty. Do we really have a choice here?
where is the consumer right?
