Bajaj Finance — false commitment

Address:

Thane, Maharashtra, 421301

We purchased sony led from kohinoor electronics shop in kalyan west. We bought it on bajaj finance emi facility. While purchasing the product, bajaj fin executive commited to provide 13000 coupons in our bajaj fin wallet. But till now we havn't received the amount nor coupons in my wallet. Customer care told that there is no such offer they are giving.
Request you to please look into the matter.
