Boost Refund

When a server is boosted, money is taken from the boosters account to support that server; that boost should stick to that server - regardless if the person that boosted to begin with has lost their nitro subscription. You are subscribed to Discord extras, you buy a boost to level the server -- why are you being charged monthly in addition to the discord extras for a server you boosted once?
I did not subscribe to the server -- I subscribed to discord.
I boosted one server to level two -- I did not subscribe to the server, I boosted it; when my nitro sub ended-- so did my boosts to the server. If my money isn't going to keep that server at that level I paid for -- I want that money back so I can at least support the artist that hosts the server. I thought I paid for that server level, it's not a subscription.
