Carrier Midea India — want replacement of defective product

I think I did a mistake by purchasing ac from midea carrier.
From starting itself you gave a dumb product and from your side ac repair 3times.
And still it's not working and if it is not replace I am going to consumer forum for making a complain for mideacare (carriermidea) LTD.
Very worst service from your side totally unsatisfied
I want replacement as soon as possible
