It started with deleting my progress every time I exited. Ad rewards, missions, coins, gems, and medals all gone after I log out. I eventually started getting messages saying all my progress was deleted due to exploiting. I spent money on gems and that was gone as well. Now my account is banned from this game. Customer service was very dissmissive and unhelpful. In addition my last review was responded to offering customer service to speak to me. Despite my complaint to customer service. 👎
