I contacted them to fix some problems I am having, like: game get freeze and I have to refresh the game then I realized I lost everything that I start with!!!! Or the add from 15 seconds changed to 45 seconds and it's very ridiculous 🙄 then after watching 45 seconds, it doesn't let you to close it, then you have to refresh it again, that takes another minute for few pennies that in the end after 3 minutes you realized you waste your time for nothing and you've lost everything again.
