Toyota — Faulty parts of new innova crysta & non availability of spare parts

Address:

Ranchi, Jharkhand, 834001

Purchased a new innova crysta last month, few days back the brake fluid began leaking, therefore sent the vehicle to Ranchi service centre on 05/08/2016, the toyota representative said that spare parts are not available here and we have ordered the same and it will reach by 8th, so you can positively take delivery of vehicle on 8th, on 8th on enquiring we were again told that spare parts are in transit and will reach on 11th and definitely we shall provide the same on 11th. Again on calling back, the representative said that spare parts are not available and will reach us by 25th, by then you cannot take back your vehicle otherwise more problems can come up and then your warranty will lapse.
Why is toyota selling cars if they dont have its spare parts in hand. Its rainy season and I am facing huge difficulties in travelling due to the same but toyota is hardly bothered for the same. They are not even ready to provide some alternative solution till the time being neither are returning my vehicle by making some makeshift arrangements so that i can use my vehicle till the time their spare parts are not available.
Its a brand new car and i am suffering for no fault of mine.
