macbook air purchase problem

In general, I will describe the whole situation to you, I ordered a macbook air for education for 899 dollars and there was a gift of airpods with it, you could add 90 dollars and get proxies instead of the usual airpods. I added. Placed an order. Things are good. The headphones were shipped out almost immediately and charged $ 249 for the full price. But for a laptop, the amount became $ 740. Well, I think it's all the same. But after a while, they canceled the sending of the laptop, writing that we were not sending to this address, (but the headphones were sent). I canceled the sending of the headphones, but they are already on the road and they can only be returned, but I cannot return them because I am not in the country. It turns out that they just sold me a gift for the full price, but the laptop was not sold. How did it happen that the headphones can send to the address but the laptop does not?
