No response – Blocky Farm Review

I have been writing to support team regarding to a bug this game has. Obviously when you start getting 4-star cards, system stops giving you 3-star cards. This is an issue because buildings like wells only have 3 level, and if you stop getting 3-star cards, you will never be able to upgrade them. This is so so frustrating! And no response from the support team. I have no idea what to do as I have already spent so much money in this game.
