who would take a garbage can?

We have been filling our garbage and recycle cans very full. Pickup was Wednesday. The trucks came and took the stuff, but our garbage can disappeared. Who would want our garbage can. Ken walked the street looking for it. It has our house number on it. Knowing the inside cans would soon overflow, even if they are big, I called the Sanitation department.

"Do you have a small can?" she asked.
"Yes." I said. She wasn't surprised.
"We'll take care of it," she said.
"what is your address?"
I told her and wondered,"Do you know what happened to it?"
"Sometimes they fall into the truck"

How often? I didn't ask. The new can still hasn't arrived. We need it soon.
