Largely due to the limited release. These are usually prenegotiated. If your low budget movie does well expect a wider release. Gl finding anyone local showing it.
It's not their fault they're not showing that movie there. Not all theaters are going show that. So, use the "internet" to search for theaters that are showing that movie there, and as you said "spend my money elsewhere".
It's not likely anyone who is responsible for bookings at the theatres will see your question here. You'll have to ask theatre corporate management.
Honestly, I'm not sure.
