Mistakenly subscribed unable to cancel.. – Running Slimkit - Lose Weight Review

I downloaded this app forever ago, uninstalled and didn’t realize it was charging me for a subscription. Now I’ve tried reading every instruction on how to cancel it and I can’t figure it out. I wish I never got tricked into this app.. I’ve contacted apple and it’s been a mess. Can anyone please help me so they will stop charging me???
