Payment issue on Google Play

I’m trying to purchase the pro version on my Android phone through the app;
It directs me to the Google payment system, and I choose the regular or other cards that I always use for my purchases. But however I keep getting the error message says

“Your purchase couldn’t be completed. Please update your Play account settings so that the selected Play country matches your country of residence.”

which is not correct. I did try deleting and re-downloading both Google Play and the Shot Designer app. I don’t have any country on my account, and I am trying to do the purchase in the same country that my Google Play settings are set to. Can’t figure out how to solve the issue. I don’t want to buy from your website because the price offered in my country is much cheaper.
