Axis Bank — Not received Flipkart gift voucher

I called many times axis Bank customer care and Flipkart customer care. Too much third class service. Last time they said wait for 45 days, some times said server is down, now they said on 16 April they sent gift voucher then I said, I not received sent it again. I not received on MSG or email. Telling a lie and not taking my complaint just wasting my time.
