Electrolux India — faulty split ac unit

Electrolux ac es18f3c (3 star) 1.5t spl - hgg024

I bought a split ac unit with above specs on 6th may 17 and in less than 3 years the gas leakage happened twice. I had to pay approx. Rs 3000 to get this fixed to the company. However as of now also, my ac is not cooling since the gas leakage could not be addressed permanently. I request you to kindly replace the faulty ac unit. I am also attaching the product invoice for your reference
