A Facebook AD for sale watches to India

Current, i have learning how to make a AD from Facebook for sale watches. First, i update one hundred new replica watches, include Rolex, Omega and Longines.
I set the AD local to the India, and i research which brand watches and which style watches Indian customers would be like it.
In my survey, India customers more like Omega and Longines brand watches, and they like metallic watches, For example, gold watches.
I create a AD, and set local to India, set the customers age between 25 to 35 years, set sex to men, set customers interest group with ‘watches’, ‘Longines watches‘, ‘Omega watches‘ and ‘Rolex watches‘. all is ready, let it going!
In two days, spend 45 USD from me, had about 38,000 India people had see my AD, had about 400 India people had click to my website. But only two people register to my website, and only one people make a order, but not pay it.
I had sent a email to the customer who had make a order from me. customer say he can not see a credit card payment to use.
I had examination it, but i can see the Visa and Master credit card payment channel. Does people in India not use Visa/Master credit card?
Current, i wait for the customer’s reply. And when i have free time, i will try make a AD from Facebook again.
