Misunderstanding with the payment

Hello! My account now shows a missing order of 70 euros, as well as two orders of 20 euros each, even though this should not be the case. Originally, I created the account for my schoolwork, which was supposed to be free, but it seems that activating the school account also reactivated my old personal account, which is why I paid 70 euros to make a 30-second video... I had previously sent an inquiry about this here, but I never got the money refunded. At that time, I did cancel my subscription, but now money is still disappearing from my account every month, even though I canceled my subscription a long time ago. You should definitely be able to verify that I haven't even used any programs. It would be very pleasing if these funds could be refunded to me and, most importantly, the subscriptions could be stopped, even though I have already done this a couple of times... Thank you in advance for your help!
