Dabur India Ltd — non credit of dividend warrant amount.

I am share holder of dabur india ltd, dil0008307. I had received dividend warrant no. 3700423 dated 16/08/2018, for rs. 37500/-. I was unable to deposit it in my account timely. So i sent original dividend warrant and my bank account details with pre printed cancelled cheque and request letter as required by karvy computershare pvt ltd unit dabur india ltd, by registered post on 07th december, 2018 to credit the amount directly to my account. It was confirmed by the karvy computershare pvt ltd. Unit :dabur india ltd, that the all required documents received by them, and amount of dividend warrant will be credited within, 10 days. But till date it is not credited by them.
