North Little Rock bulk pickup question

I'm sorry if this is a dumb question, and it is NLR-specific, but I can't find a logical answer online.

According to NLR's website, bulky items are to be picked up on the normal garbage day, which for me is Wednesday. I put out a small piece of furniture I no longer needed - a cat litter box enclosure - next to my trash and recycling, and nobody came to get it. I called NLR, and the gentleman there said my pickup day was actually Thursday. Fine. I was told I don't need to make any kind of special request, and that it would be picked up.

Thursday came and went, and nobody picked it up. Any tips? Do I call 311 in NLR, or is that just LR? My neighbors put out mountains of things, and they generally get picked up.

I had this problem once before with an old, broken grill, and before I could sort it out a random person saw it and grabbed it.
