No customer service to help with problems – Studycat: Fun English for Kids Review

I purchased this app via Apple App Store on April 13th 2020, to help my kid with his English since with the covid emergency he is not getting his English classes in school. In the advertisement it was stated that the monthly charge for the subscription would be of 6.99 so I decided to get that after enjoying the free trial for a few days. On April 18th I got charged 9.99 plus 1.11 in tax, first surprise! Then on April 20th got charged 7.79 (6.99 plus tax). The worst part is that everything my son uses the app we get a message,several times offering the monthly subscription, which I already payed, or the yearly one. I click on the restore purchase button and it does not help at all. I have also deleted the app and nothing. My other concern and the reason I will be cancelling the subscription is that my son is not receiving new challenges. Once he completed all of them the app does not seem to offer more. I have emAiled the app developers several times and have not received any response. I liked it at the beginning like another user said but quickly I realized this may be a scam.
