My infusion sets were stolen

I just checked my apartment's lobby to see if my infusion sets had arrived and the box was cut open and the infusion sets were gone.

Now I don't know what to do. I can't get into contact with the medical supply company I buy them from till tomorrow and I'm not even sure who else to tell. Tandem will probably just tell me to call the supplier, and I'm sure my insurance would just tell me the same thing. Has this ever happened to anyone else? How did you resolve it.

Honestly I'm kind of freaking out. I don't want to go back to MDIs but I don't know what the alternative is one I run out. I've only got like 3 left. Maybe it will all work out, but I can't help but get emotional about this. I wish I could just pick this stuff up at a pharmacy, I've never had my insulin or test strips just up and disappear.
