bluebird by amex alowed an un othrised charge to be drawn out Internet

last month i had microsoft try to pull out 9.99 for the xbox live i did not othrise that. i called them and they sed they took cair of it and then i called bluebird by amex and they refunded my money that day no problem .well the next day i woke up and the 9.99 charge was there agan and yet agan i called microsoft and they sed that they would fix the problem and they clame they did and then i called bluebird by amex and this time they told me it would be 8-20 days befor my money would be returned to me. i bit the bullet cause it was only 9.99 but while i was on the phone with them i told them to note that that charge from them was an un othrised charge and to not let it go through ever agan if they try to charge me agan. well here it is a month later microsoft did it to me agan tryed to take 9.99. i called yesterday and they sed they fixed it and i called bluebird by amex and they refunde my money that day while i was on the phone with them and low and behold i wake up today and they have alowed the 9.99 charge to come through agan. when i called they sed i would have to call the merchant cause they have no record of me calling the day before and no record of the 9.99 being returned to me the day before .so i call microsoft and they say that it was refunded and that my card should have the money on it because it was taken from there account yesterday. so why is bluebird trying to say they cant give me my money it was an instant trans action threy have receved the refund so where is it and why am i being billed agan for it? they say they are wating on the merchant yet the merchant says the refund is allredy approved and has cleared and they have not charged me agan
