I had booked 2 moto 4g plus phone cost of 11500. I paid 1 by credit card 1 by cash on delivery in amazon.
1 mobile delivered at that time executive told it's a cash on delivery i paid 11500 and collected the phone and another one still i didn't received and from 2 days i am getting message like mobile will deliver today and have to pay cash again.
As i told before 1 mobile i booked by paying through credit card.
But i don't know why i did't received another phone and don't know why they asking to pay cash again.

I need support from your team for getting mobile delivered which i payed through credit card.
