Free Trial Can’t be Cancelled – InstaFit - Home Workouts Review

I need help canceling the free trial but nobody is answering. I called the phone number +1 415 610 5615 that is non their website but it is disconnected and they are not answering either on WhatsApp. I need this resolved today as I can’t have the membership for this app charged to my credit card.
