Burger King sold me a meal but had no drinks yet still charged me. No refund issued. Phoenix az Arizona

I went to Burger King #5160 at 12:09 pm on October 21st. I purchased two combo meals and upsized the drinks. They didn't tell me until after I ordered that the drink machines were down because they had no water so I would have to drink tea. I was fine with tea but that was empty too. Only beverages they had were the slush drinks and I asked the assistant manager Angel if I could trade my to unavailable upside drinks for one of those and he said no. I then asked for a refund on the drinks and he said no. I then asked if I could at least have the upsize fee back or a raincheck for the drinks and he said no again.  

I said what did he expect me to do since it's hard to eat a meal without a beverage he just smirked and said not my problem. I sat there for a bit to see if the drinks would start working again but they didn't. They went on to do this to many customers and when they asked for refunds the assistant manager Angel said no. 

They could have at least put a sign on the door about the drinks or told you when you went to place your order but they didn't. On my way out a customer was loudly complaining about it and Angel told him to get the F out of his store and never go to any Burger King again.

I called Customer Service but don't think they took my complaint seriously since in their words "It's just a drink". I take that to mean they are okay with ripping you off and just smirking and saying "Not my problem".
