It's a little bit complicated rather than try to use the local exchange site to buy ethereum consider that needs easy requirements. Remember a lot of banks have been blocked all of CC that has been used to create any transaction related to the cryptocurrency.
Personally i prefer to buy eth from local exchanger, i give local currency cash value to him and he sends me equivalent amount of eth to my wallet, this for me is the most trustworthy method uptill now.
I'm always using this method too because it's more convenient for me personally.
