Planner Plan 3 Subscription Cancelation and refund.

Hello.

I have Microsoft planner plan 3 subscription which expired and has been automatically renewed which is against my intention , I tried to communicate with Microsoft support through email , live chat , phone call but without any positive progress , on phone they have an AI agent which is wasting of time , in live chat they just pass you to another departments and share wrong email address .

I have been trying to fix this issue since the first day of subscription renewal but so far nothing .

The subscription is under a twin alias email which I don't have access to and there is no admin , the email is under onmicrosoft domain.

I need a urgent quick help for this issue so that I can get refund .
