Amazon India — Cashback not received even after 45 days of actual date

Address:	Raigad, Maharashtra, 410210
Website:	www.amazon.in

I had ordered the item order #[protected]. (Oneplus 3 mobile)
Using promotion going on with statebank card.
The cashback was supposed to be delivered by oct10 2016, yet its not credited to my account.

Every time i contact amazon they just ask me to wait.
Its been 45+ days now, i m yet to get the cashback

Few of them say its been initiated few say its pending from bank, but none of them giving me any resolution.
