Triple charged?

Ok I recently got back into playing runescape, only 2-3 days ago, and then when I tried to get membership off my moms credit card it denied it twice, then I tried a Debit, it denied the first time and accepted the second but now I look in my Yahoo and there are 4 emails from them will they charge me for all 4 attempts or do the emails mean nothing. I only got 30 days of membership

btw its the email saying the verfication code and stuff.

 

If they got denied, then you will only be charged for the one.

 

I had the same problem and they didn't send my money back.
