Apple India — MacBook Pro

Address: Gangtok

I purchased a MacBook Pro in September 2019 where I took a consumer durables loan from HDFC, after 120 days I was assured a cash back but it’s been more than 9 months and I haven’t received any cashback, I even talked to the representative but they claim they have disbursed it but they can go through my account details to see I haven’t received it yet.
Any help would be grateful.
