Carrier Midea India — Complaining about getting bad product not working.

Sir/madam
My uncle gives an AC on my brother wedding as gift which he bought from quick enterprises Rampur UP 244901 with invoice no.697 HSN/SAC code 84158210.
As its an october the climate has changed we didn't installed we have now in april installed it which didn't work because we have got faulty indoor unit of ac we contacted to the company for changing indoor unit but they said it will only be repair then they said fan motor is not working its takes them 25 days for fan motor to changed but it still didn't worked and again they said its PCB isn't working its take 10 days more.
I am cheated by where my AC has bought and company is also not helpful its of 41000/- its a big amount for me but they didn't have any pain.
Thank you and help me
