I am from Lahore and I booked a 1.6 Corolla Altis in Super White on 14th November, 2015. I only made Rs. 5,00,000 partial payment. The delivery month they gave me was May 2016.
I paid the remaining amount of Rs. 15,45,500 on 11th April, 2016. This includes the increased Rs. 25,000 for the immobilizer etc. I was not asked to pay the extra Rs. 20,000 which was the price increased by Toyota Indus back in January-February as they said my booking was before 1st of December 2015. Today I got a call from the dealership and now they are asking for Rs. 20,000 saying I have to pay it. What should I do?
