Hi Billy, To clarify "switching off ads" with any purchase only ever relates to third party ads, and messaging related to this should reflect that. This means upsells relating to the app itself, and information and cross promotional interstitials and banners such as the Into the Dead banner in the inbox screen will remain. Sorry if you feel you have been misled with respect to this. If you contact our customer support via the app, they can walk you through the refund process.
The game runs great on the iPhone 5s running iOS 9.2 I just updated. I'm still seeing ads for the accelerator pack when I already have it. I think the kits are a bit expensive. It's going to be a while for me to save up 5k purple crystals lol. Game really is fun though. I like the global tournament. It genuinely a fast paced and fun game. Billy
