Sony India — playstation not working and replacing

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201306

My uncle brought a ps4 for me 2 years back from usa and it being a gift he did not give me a bill, obviously now after 2 years my ps4 just won't start and i went to their service centre to get it repaired and i obviously did not have my bill so they refused to even replace it.. What kind of a blatant disregard do the people of sony india has for its customers? I was seriously pissed off and tried to register a complain on call and they refused to do so..
I should have brought the xbox one x
