I purchased the level boost and WGT charged me 400 hundred credits for the 2nd time and level or boost was not achieved. Here I go again, another 4 months of watching videos for credits so I can afford a sleeve of balls. Ok, so 1 month of watching videos for a sleeve of balls. Seriously, so hard to get anything from playing but fun. No credits, no upgrades and nothing but eligibility for "purchased upgrade." I demand some compensation!!! (love playing though... :))
