Daikin Air Conditioners / Daikinindia.com — Complaining about split AC

I am very sorry to say that i bought a daikin split ac last year in july that time they didn’t install the outer unit properly and it started making too much noise... Initially it was soft and now it has increased its intensity... Last month i put up a complaint also for this... Did some temporarily solution for which one week it was ok and again it started giving me the same problem... On 23 july 2020 again i complained nobody wants to come and fix the problem... It’s so irritating now... If my problem shouldn’t be solved then i won’t keep quiet...
