Money Order Mix-Up at toot-n-totum on 34th and coulter.

Ok so I asked for a money order for $300 bucks ealier today at toot n totum... well I just got home and I noticed that the cashier gave me a $200 dollar money order instead of $300...well I double checked and tripled checked the receipt and they gave me only (1) money order for the amount of $200 but they took off $300.79 from my card....so seems like they messed up the amount...I'm not mad at them cause mistakes happen, i'm just mad at myself for not catching it before I left the store. Well lesson learned for me. I just hope that they can fix it in time cause that was rent money.
