Serious problem from support team. When I fully charged the booster but it won't let me use only showed "No yellows to use" and end up I lost my SE booster and perks. Contact the support with photos. The support named "Illario" didn't even explain just blamed on old hardware. This pissed me off I have newest phone with all updated game and I replied back asked what "No yellow to use" is the guy just copy and pasted same thing all about old hardware. You guys need look into who works there.
