http://adzbuzzhelp.com/ I did. Still no any help. About 6000 coins went to the abyss.
I am having the same problem, also contacted support, and also the buzzpower i purshased in the past are gone. Lost ADZ and lost buzzpower

Nobody lost their coin. Its just that they are not showing when adzbuzz is accessed from a PC. if you try to access from a mobile, you will see the amount of coin that you have. Maybe in next release that will be taken care of.
