Maruti Dzire
Delay in delivery

I booked Maruti Dzire on 14th April by 10, 000 /- to Vipul Motors, Noida.

They assured me to deliver in 4 weeks at max..

After 4 weeks, they said to deliver in 10 weeks and after 10 weeks they again said to wait till 31st Augus.

Would like to know waht action can be taken
