You spent the money as you saw fit, so no you won't get a refund. It would be one thing if you spent money on something that was broken or was wrongly advertised or charged hidden fees, but they didn't. You simply chose to put this much money into a game like this, so what you're feeling is "buyer's remorse". It's not the company's fault that you decided to spend that much. The game does not require you to pay anything to access any of the features. I have a grudge against P2Ws that pay as much money as you have yet expect sympathy for paying that much in the first place.
