transaction charged twice.

Hello,


Two days ago i bought from your website at value 215.60 dedic. 
 
I used my credit card to pay for 215.60 for those service.
 
Yesterday morning when I checked my account, I had the transaction charged twice.
 
I have attached my bank statement that shows the double charge.
 
Plase let me know how and when do I get the second charge credited back to me?
 
Thanks
