What company delivered them? It may not be the fault of Underground...wait & get all the facts. I've had several things shipped to me with tracking, that
like with yours, said they were "delivered"...but NOT to ME.

It was NOT the company's fault that I bought from, they were correctly addressed...but it was
the fault of FedEx, for failing to correctly read the delivery address & get them to me where they belonged. Annoying for sure...especially if you're out of rats.
All delivery companies, whether UPS, USPS or FedEx, push their employees for speed of deliveries, so it's easier for them to make mistakes...they're humans.
If Underground is a good company, they'll put this right promptly & I hope they do.
Another possibility (?)- could they have been left at your door when you weren't home & then stolen? That's another "thing" that's happening in many areas-
thieves follow the delivery trucks & help themselves after they pull away. People have caught such incidents on security cameras...and rats are probably not
what thieves expected to get either.
