Apartment ac filters for our unit

I am genuinely beginning to get aggravated with my property complex, why? Because they never seem to have enough air filters, but usually when it is time to replace the air conditioning filters in the apartment’s Heating and A/C system, I would go down to their main office and get one from the front desk, but it seems like they never have any available anymore, however they are consistently out, and then they would tell me that they will be getting them in soon, however they never do, however it is genuinely frustrating, because not changing the air filter often enough is going to take its toll on my heating and cooling unit, and it’s not tolerable for my cooling unit to suffer just because they don’t have enough filters available. It genuinely got so excruciating to the point I genuinely had to go out and buy my own, just to replace the outdated air filter. I called and complained, and that seemed to help a little, as after that my associate and I was able to get an air filter for a couple of weeks, however it didn’t take long before they were out again. Why are they consistently running out of air filters? They don’t even have that many renters here. Unless they have someone who ends up taking most of them, or they don’t buy enough, however anyways, that is my only complaint about this locale, because everything else here is pretty nice, even my house owner is a cool person, I just wish they would stop running out of the Heating and A/C filters here.
