What should I do about my apartment?

I renewed my lease in June and with that renewal came upgraded appliances (and rent increase of about $300). A few months later, I moved into another unit and was told that they would switch the upgraded from my old unit into the current unit that I am in (it has outdated appliances). I was told this 6 weeks ago (I moved to the new unit on 10/1). This has yet to happen. Despite the current unit having outdated appliances, they charged me the rent for the upgraded package. I paid it, thinking they would switch everything sometime this month. I just got the rent balance for next month…and again, I’m being charged the new rate for the upgraded package.I emailed the property manager yesterday and I’m waiting for him to respond.Do I have any recourse in this matter? I really don’t want to pay the increased rent for next month again while they take their time to hold up to their end of the deal.
