Vostro 15 3510, not satisfied

I bought Dell Vostro 15 3510 laptop 2 months ago and it's build quality is very cheap for its price. a 50 omani rial laptop is more stronger, one of the hinges is broken and the shop guy said its misuse HOW?! if it's misuse there will be marks and I was using it very carefully after the shop guy didn't help us we went to some places in hope to get it fixed under warranty than Al Khalili Buildex took to fix and we are waiting for parts but my heart is broken and I don't want it anymore.
