Beware this is a fraudant company, i had insured my google pixel with them, they refused to give me the claim hence i told them to return the money back to which they asked me my bank account. After giving my bank acount to them i mentioned below stating a please, do not fool people, as i was fooled to which the person, who was replying to my mail stated that only fools dont understand.
How can any employ of any company talk to its perspective clients like this? This is totally disgusting behaviour and that person, infact any organisation which does not respect the customers should be blacklisted with immediate effect.
