Ok Yankee, just to remind you in a few lines,

this is the error I received at mtgox.com
"This code cannot be redeemed (non existing or already used)"
Account Number: M29343117X

OrderID: a0b11d2c-8239-4f79-8cff-323dfafb691b

Thank You! Really appreciate your help. I hope to see this resolved by the end of the week.  
Anyway I look forward to buy more BTC this year.
