The developer is just borderline scamming players. I am having no report/alliance tag bugs for almost a month after they are notified. Meaning can't see bunker drops or joining alliance fights. Support says each time working on it but nothing happens. Refunding requests are simply ignored. So, don't buy any chests. Maybe you will be able to step one step ahead. However, if you are just as "lucky", the $$ is just thrown away. Worst ever support I have had.
