Help me please

good day! On February 26, I downloaded the Itranslate pro application and wanted to try using it, but there it was stated that the program was paid and you could only use it for a week for free. I chose this week but after that billing information was required. I did not like it and I immediately deleted the application and did not use it for a single day. Now the ITranslate Pro application is trying to charge my annual subscription fee of $ 40! despite the fact that I did not order a one-year subscription! help me please! I don’t want my payment taken for something I didn’t ask! Now I can not update and download applications! Everything is stuck because of itranslate pro (((((I hope that you will help me and cancel the payment request! Many thanks in advance!
