I did 2 surveys for manager coins and when I finished, I told me that I had received the coins and when I was logged in, nothing was received when I clicked on the support it said the coins are already delivered but that is not the case
In Game Valuta
Q: I did not received the boss coins from the special offers, what to do?
A: Offers from Business Club are responsibility of our partners. You can check the status of your offers on every offer wall by clicking on bottom on Support/Miss coins link.
You can also contact them via same process if you think that it's taking way too much time (some may take more than a week to be completed).
There is your answer.
