So, I didn't know how to search for this problem I am having so I decided to open a question. The thing is, I bought linden dollars more than once, always using my paypal money, but now I just found out that it didn't only took my Paypal's money, but it also took my credit card's money.
Yes, yes, I have enough founds in paypal to cover all the lindens I bought, I just can't understand why it also took money from my card, it's really confusing. Thanks to everybody who replies to this beforehand, I apologize for my bad english!
