i've bought 2 silver keys in the shop for 80 gems each, but they didn't appear and i still can't open my silver chest. fix this, please

I buy two golden keys and game stuck and after reload keys disappears and gem deducted

I bought some keys, my gems were used up, but the keys never appeared. I demand that my gems be returned and that I be compensated.

I've just bought 2 bronze keys and left them as bubbles and rejoined the game and my keys were gone.

I purchased two gold keys from the store and I logged in today, they are nowhere to be found and we’re not used. Please refund $270. Thank you.
