I want to cancel my subscription to Picsart

I want to cancel my subscription to Picsart that I never wanted in the first place. It is up for renewal on the 22nd of this Month. There is NO where to cancel this! There is no place in my subscriptions under my Apple account/iTunes nor is there a place under the settings in the Picsart app. It gives me the run-around. It asks me why I want to unsubscribe, I click a reason and then it gives me 2 options- to resubscribe or to resubscribe. This is beyond frustrating. No other subscription I have had through the App store has ever not allowed me to cancel like Picsart. It is a scam. I am frustrated and I don't want to be told to go to my iTunes/Apple account to unsubscribe because there is NO place to do so. I am sure I am not the only one having this problem. I never used this app because I was charged during a free trial period a year ago. I am not paying another $60 for another year. Does anyone know the solution for this? TIA
