Anyone else unhappy about the way "Calm" charges a subscription after only 4 days "trial"! I thought, like the other apps I bought that I had 40 DAYS!! UGH!

Longtime Windows phone user just switched. Spent a day looking at a few apps, and ordered 2, the first, Breathe, gave me a 30 day trial. The second, Calm gave me what I thought was a 40 day trial. Great - I'll try them - right. I was surprised to see a $76. charge today from Calm, for what they said was the end of a FOUR day trial period, and I was billed a 1 year subscription! I don't think I had any opportunity to choose a particular subscription period! What kind of business does biz this way!?! Not happy! Any thought on how to get my money back. Calm puts it entirely on iTunes/Apple apps store's back! iPhone gave me just an automated response... Is there anyone home at Apple? Now I understand why they are so greedy and rich! Alas... Too bad MS didn't stick in the phone biz long enough to give them a run for their money..Such a bad first experience...

Otherwise love the phone - works very much like my Alcatel Winphone… curiously, the same size as the XR! though made over 3 years ago!
