Address:

396191

Due to heavy rain on 28-8-17, in vapi gujarat, my 4 month old innova crysta reg. No. Gj 15 cg 6406 affected by flooded water in parking.
I sent it to nearest dealership rathod toyota on 29-8-17 at around 4.30pm.
Since then i am vigorously following with rathod toyota to get repaired my car in time.
And, they are following up for original parts with toyota, but toyota is not able to supply required parts.
Now, its almost two months, my business suffering, and most important thing is my diwali vacation will be ruin.
I need my car back with original state by 17th oct. 2017.
Else i will be filing case in consumer court for non supporting and mental and physical harassment.
