Scam App - MuscleBooster

How is MuscleBooster still allowed to offer its product thru the app store? I see 100's of complaints about excessive or sham charges, non-existent customer service, difficulty canceling, charges after canceling, etc. Yesterday, September 29th, I signed up for a 3 month trial for $19.19, this morning I get up and I am looking at 10 charges from MuscleBooster, individual charges ranging from 19.19 to 162.30, total charges of over $600. Some of the charges with a submission date of September 27th, 2 days before I had even heard of MuscleBooster. No surprise, their website is a black hole, no effective way to communicate the issue much less fix it. I purchase thru the App Store and thru Apple in general because I trust that Apple is vetting the suppliers it allows to use its platforms to make money. Apple needs to clip MuscleBooster, its parent org, and all the other garbage suppliers like them.
