HDFC Bank — cash back not received

Address:

Kothanur , Bengaluru, Bangalore, Karnataka, 560077

I had purchased an I phone from Poorvika mobile on 05 April 2019, using a HDFC card under the cash back offer. Till date the cashback is not received.
please look into this issue.
The HDFC website does not have an option to register a complaints for cash back claims.

thanks
