Earn gems scam – Robot Merge Review

So, I did an one of the “Earn gems” offers and signed up for Magic Piano about 4 days ago and still haven’t been credited my 2204 gems. The offer says completed and awarded but nothing. There is no way to contact the ad site and no customer help in the game at all. I don’t appreciate being cheated with no way to resolve the issue. This has lowered my rating from what I originally put.
