I didn't receive my MacBook Air order

I made a purchase on the website for a MacBook on August 23, with delivery scheduled between September 3 and 5. Purchase order number W1*****60, after checking the tracking code on the DHL website, I was informed that the delivery took place on the 30th, and that it was received by a person named Mathis, however, when I asked at the hotel reception, they informed me that they had not received anything yet, what should I do?
