I now need a new air conditioner

I have a new mattress. It's very nice. Now I need an air conditioner but not one with wifi because why do you need that? I just want my whole apartment to not be an oven and to not have to drag it up the stairs.

I tried to get an air conditioner with Affirm but Walmart delayed the order because the one unit was damaged so I had to cancel and affirm might not let me buy through them

How can I possibly be rejected for non payment when I didn't even get a chance to pay more than a huge down-payment!? Which I must wait 3 to 5 days to get back. Arggg
