AT&T Received Empty Box!?

I pre-ordered the Galaxy S9+ on the 11th of March. The phone shipped on the 13th, I received the package on the 14th, the box was empty. I called AT&T customer support and went through eight different representatives none of which told the following representative what my situation was. I talked on the phone for 2+ hours only to find out that I "might" receive the phone I pre-ordered (which anyone can go pick up in the store on the 16th of March) in 7 days. I paid $900+ for a phone that I now have to wait longer than an average Joe has to wait to go buy in a store. I am extremely dissatisfied with AT&T's customer support, the fact that I received an empty box should not be happening to customers. I asked the last representative I spoke to to give me a compensation for my inconvenience and loss of time; he spoke to his supervisor and told me that there was nothing he could do for me. I 100% would not recommend AT&T to anyone and I will not let this issue go ignored; I must be compensated.
