Customer support doesn't respond and doesn't refund money.

I accidentally approved an annual subscription and realized it immediately. I submitted a refund request right away without intending to use the subscription, but it was denied. This was an honest mistake, and I contacted support as soon as the charge appeared. I have now emailed the Flo support team and sincerely hope they will review my case again and make a one-time exception. I would really appreciate fair consideration of my refund request. I've contacted your support team everywhere, and all that's left is to write a review because you're not responding at all. I'm demanding a refund. I really need the money. Once you return the money, I'll correct my review and rating. I'm waiting for a response. I’ve sent you another email regarding my refund request. Please check your inbox and reconsider my case

Lost money and couldn’t get it back

I downloaded the app, used it for a while, but every time I opened the app I was bombarded with offers of prolonged free trial. I must have accepted one of them, but didn’t notice the fact they would charge me for a yearly subscription. Because of the fact I rarely opened the app and didn’t check my subscriptions, and wasn’t notified before being billed, I got charged a lot of money. Contacted Apple to get a refund, but was denied my request, twice, even after explaining my reasons. I guess it’s my mistake for being inattentive, but I want everyone who reads this to beware of their manipulative tactics, and always check everything. Think twice before getting a free trial. Thank you for your attention.
Developer Response
Hi Belieall! We’re sorry to hear that! The only way a user can sign up for a subscription is by tapping Continue on a screen that offers Flo Premium and confirming their consent with their password or Touch/Face ID or by subscribing at app.flo.health. If you contact us directly from the app (Menu - Help - Contact us), we’ll be happy to help! Flo Team
Wonderful!

Well, so much is said about the app and this is actually very good. But hopefully the creators will add a feature (on the eve of the New Year) like “finals of the year”. I mean I really would like to see something like “this year you had sex 30 times, good for you!” or “there was not a single one delay in your cycle all over the year, what an amazing achievement!”That would be funny as well as interesting:)
