Purchases

I tried to get purchases this morning, I put my apple password in but kept getting a message saying “due to European legistration,” they asked my bank for authentation which said my purchases were denied, so I to try again which I did 4 times eventually I got purchase that I wanted then only to find that I could not get on the site I wanted & lost the game, but when checking my e mail to my shock I have been charged 4 times but not receives all the lives, what is going on is there some kind of scam

i would like the money back that I was charged
