They asked me to keep misdelivered cuttlefish in my freezer??

‌I ordered some cuttlefish online..
It didn't arrive at the scheduled time, so I searched for it and found out it was misdelivered to a different area..
When I spoke to the company, they confirmed it was a misdelivery..
They said they would send a new one right away,
and if the misdelivered item arrives at my house later,
I should mark it as "Return" and leave it in front of my door for pickup..
When I asked if I should just leave it out, they asked if I could keep it in my freezer? Haha
How am I supposed to do that...
I told them I'd just leave it out and asked them to pick it up quickly...
The misdelivered product eventually arrived, so I put it outside just like they said..
But they didn't pick it up?
It's been sitting outside all weekend, and now my kids are complaining about the smell...
Sigh..
This is killing me...
