donation Problem

Good morning, I'm from Paraguay, I made the basic donation of 10 euros last week, on Saturday, February 9 to be exact, the payment was made 3 times since the page told me to send me as if I could not make the payment , they call me insurance of frauds of the company from where I remove the credit card used and they told me that € 30 was debited in 3 successive payments of € 10 on the page of warmane games, to which I said that if I was in knowledge of the operation but I repeated the payments why they were not made, they asked me to wait between 24hs and 48hs to see if they did not arrive or the return of money from part of the page or if I was not credited the account ... Finally, I would not like to lose 30 € so I ask if there is a solution for this situation, I thank you, if my English is bad, also excuse me, use the Google translator to try to communicate...
