Girias Investment Pvt Ltd — onida air conditioner/ bad product/ wrong installation

Address: Bangalore, Karnataka, 560043

I have purchased onida ac in 2016 april from girias hrbr layout. First of all the installation was not done properly, the guy who had come was not sure about installation but somehow he did it but the water outlet pipe he just did not fix and just kept it down. After that we started using this ac and used it for hardly 15 days. And then we used it once again in 2017 march but to my surprise it did not work. Then i called onida customer care and they informed me that the wiring was not proper, they did something and then it started working. We use it for another 20 days and after that once again 2 days before. And then i had to call onida person to check this error. He came and informed me that mother board is burnt. This ac is one year old hardly used and on top of that it is inverter a. C. How come the power fluctuations could harm this. Moreover my building is secured for such issues. The onida guy said that wiring was not done properly and a single wire should have been used. Now i am just requesting one thing please take back this a. C. And give me some other company which works fine. I believed girias person who sold me this and bought this and now i am in trouble. Please help.
