Toyota — Defect in new car purchased

I purchased and Toyota Glanza in Oct 2019 from Toyota showroom. But right from that day I found a major issue of car getting discharged within 24-48 hours. After that I made several complains to the company. Than they used to do something or the other and used to say your car is not running much which surprised me as on an average 30 km is running daily. From then I used to go on regular complains and in every service I used to state the same issue to be solved but they use to charge 8-12 K every time and stating the issue has been solved but still the issue is not solved. after 1.5 years technician said that there is an issue with the battery so you need to replace with a new one I was surprised just within 1.5 years i need to get the new battery for new car. They gave the price which was quite high compare to what we purchase from outside which i did from an Amron Showroom. I thought now the issue will be solved but all in vain the issue still persisted and then agin I raised complain but still no resolution this is going on and now I am totally annoyed after spending money so much I purchased a car wher I cannot take my family in it outside thinking of if car does not start than it will be a problem. I have submitted the car to Toyota service station and will not take it bake until the problem is solved. I want the money back or Car to be replaced with another one immediately.
