I recently wanted to buy some tankicoins, but later changed my mind and didn't complete the purchase. I closed out the tab where I actually buy the product, and later came back to check if the card info is still there. It was saved without my consent and knowledge, and could not remove it at all. The card info is not saved on my browser so why is it saved on tanki's site/database without me even knowing. Is there any way I can remove it permanently. I don't care how secure or safe the transaction company or tanki database is, I want the card information removed asap.
