On Booking date 28.6.2017 Evening, Arasu Hyndai Exchange department person taken signature in varius Exchange processing catalok and came to my house immediately and taken my old car with original RC book and Original Insurence .After that I have tried for remaining amount of Rs 4.5lakhs through various banks. But due to some IT returns fillig thay are not willing to give loan. I have contacted Sales person hyndai on 30.6.2017 evening to stop processing upto 3.7.2017 for furthur proceeding and also told sales person that if loan not sanctioned as per my requirment I will go for cancelation my order .Due to some personel reason and loan problem today I have gone to Arasu Hyndai Trichy showroom and given cancelation request form.
