Not user friendly/want to cancel free trial!! – FX.X Lens.Light Flare Effect.s Review

Can't find instructions, and cant find customer support info on this app to cancel my 3 day trial...when you click on it it says can't connect to it...I'm on my iphone...I tried both my wifi and LTE CONNECTIONS and neither work! So how are you suppose to cancel if you cant get a hold of them?? No other icons within app that I can find to contact them. So don't charge me the $24.99...I dont want this app!
