I bought a Macbook air on 30th of August with master card from Apple Online Store. I've read that Apple first reserves the money in the bank and approves the credit card. Then once its approved, they draw the money from the bank and ship the product. It went on like that in my situation too, however it seems, the money that was reserved was driven two times, in 30th of august and 1st of september. The shipment is going on smoothly, and they've only shipped one macbook air, not two. What should i do, anyone have an idea?
