bed bugs in my apartment

Recently I've discovered bed bugs in my apartment and told my rental mgmt. I live in a free utility complex and they handle pest control, but are trying to make me pay $250 for bed bug treatment pest control. The mgr said there's no way bed bugs can travel through units and that I had to bring them in myself. But one of the workers for the complex told me my neighbor had them really bad. Everything I've read online and people that I've spoken with say that bed bugs can travel to other apts and this mgr is just refusing to pay for the services. Please help. What's my options here before I pay $250. Thank you.
