Lloyd — AC is not working properly from Day 1

Address:

904, Surya Kiran Building, K.G. Marg, New Delhi – 110001. (INDIA)

I have bought lloyd AC from reliance retail last yearv on 11/04/2022. From the very first day it had stopped working properly. It was not able to cool even a small room. I had raised so many complains but all in vain. Company guy visited and said it will work fine now. But after 1 week or so it stopped working again. This cycle got repeated so many times.
My last whole summer was without AC only though I had bought one. It was a total harassment for me whole summer as i was chasing company guys for whole year and now I don't want to spend summer without this.
Please refund my money as even after so many visits it is still behaving the same way. Even the company guys said that there was some problem with AC and it cannot be repaired.
Please refund my money. I don't want to get more harassed.
