Cannot cancel Linkedin Premium subscription, because iTunes does NOT proved a cancel option.

I cannot cancel my "free one-month trial" Linkedin Premium subscription, which I purchased through iTunes, BECAUSE iTunes does NOT provide an option to cancel!!!

It is NOT true (as Apple Support so nicely claims) that the subscription is already cancelled and will not renew at the end of the "free one-month trial." I guarantee it WILL renew, and then I'll be forced to ask Apple/iTunes for a refund.

Please help.

This question has been asked in the Apple Community so many times, and NO ONE seems to have an answer that actually works.

Apple/iTunes developers -- HELLO!!!
