This is to advise potential buyers of phone in CHYZON STORE in Kaduna to always ask for warranty when buying phones in the store to avoid unpleasant surprises in case their phone has any fault! A friend bought a Nokia lumia 800 windows phone in January 2013 and the phone went stone dead sometimes in October.Believing that the phone carries the usual Nokia warranty,my friend proceeded to the nearest Nokia care centre only for him to be informed that the phone is not meant for the Nigerian market and thus,it dosent have any warranty. Dumbfounded,my friend went back to CHYZON only to be educated by the owner that the phones he sells are normally sourced outside the country and dont have any warranty! This is just to advise potential customers to beware.
