there was a mistake in my mall purchase.

Hello, there was a mistake in my mall purchase. I bought the wrong warehouse. I originally planned to purchase the tradable warehouse and the currency warehouse, but my English proficiency is limited, so I made the wrong purchase and ended up buying the non-tradable warehouse and the gem warehouse. So can you help me? I have sent the relevant email to support, but only received one reply and there has been no new progress. Could you speed up the progress? Because the mall is on sale and I'm afraid of missing it.
