The best ac but the worst service. Review on O General Air Conditioner

I bought the o general ac about 8 days ago and I didnt got any response from the itself to install the split ac after about 7 complaints on help line the installer arrived they took 2 days in which they didnt worked on the wiring but did srewing up though we noticed that they sent photos when they were installing it when we complained about them we came to known that they were trainy and on the 3rd day there technician came and said this ac is very high tech and it cannot be installed by us then they tried and some how they managed to install its wiring they took the whole day again in it. We also notices that they were in tie up with the general and they from easy way company. They broke our wall even and even at times said that the machine was not good and was defected from the company and today is the 4th day of them in our home and they just created a huge menace at our drawing room.
