Toyota — I am complaibout the problem of a new corolla altis car

I, Nithin Joseph, the owner of the corolla, altis which was bought on Nov 23th, 2015 from Amana, Toyoto, in kannur, Kerla, India. After a month, the car was purchased onwards an alert message was showing saying "oil low". I consulted the in the showroom and they filled the oil and told that they will talk to the toyoto company.But there was no action from the Amana dealers. Later also the alert message contuined to show . Now the altis is in the Amana service centre in kannur.
I am a reputed P.W.D Contractor and I handle lot of cars of differnt companies .I have verna, I 20, baleno, nissan, creta, honda city. but i never faced such a bad treating from them. I was so attarcted to toyoto company and bought coralla altis for my wedding.Many people asked for the opion about the car to buy. But I am sad to inform that, altis was an dissappointement for me .so i could not give a good opinon about the car. Many times I had to stop my journey in the middle because of this"low oill" issue.
I cannot contiue with this problematic car .You have to take back the car and give a new one. or else i file a case in the court .
I, believe that you will see through this problem and take a action soon as possible.
