Never A Win

This is absolutely unheard of, i deposit and deposit and never one cashout ? The games rythems dont even look right. Its like the slots are controled or regulated in such a way making it impossible to actually win. I love my slots alot and love the GV games but once the games do what ive been experiencing it takes the pleasure right out of it all. Had a lot of hope for GV seems they only let their players down.
