Purchasing packs and getting errors

Today I purchased 1 gold and 1 silver REQ pack. When the transaction was being made there came in an error for me and it told me to try again later. So when I tried again after a bit I could buy more and I did, but I notice that it still deducted the money from the 2 failed transactions. I went to xbox.com for assistance over the error codes and they help me troubleshoot my Xbox and I got some of the money back and they told me to go on the forums to see if someone can assists me about this issue and to hopefully recover back the missing money or get the REQ packs I failed to receive.

Thank You
