Lenovo — Cashback not credited

Address:

Lenovo Exclusive Store - S V Computers N Gadgets, Nellore , opposite kanaka Mahal center

I purchased laptop on October 30 2021 and during purchase they said I am eligible for cashback offer of 10% that is 4300 Rs if I use yesbank credit card during festive sale offer
But after purchase they said I am not eligible for the offer. This kind of attitude is not good for prestigious company.
Please check my order and take action on manager. Or give my cashback.
