Need to End Subscription

I don’t know why I am being charged a monthly Miro subscription, and I would like to cancel the subscription.  I have 2 accounts, one is Enterprise level through my job, and the other is a Free account for personal use.  In either scenario, I should not be paying a subscription.  But I can find no evidence in my profiles for either account about my billing status, I can’t even locate the billing feature since it doesn’t appear in the left hand menu.  There is no customer support phone number to have someone help me figure this out.  Has anyone had the same issue, and how did it get resolved?  Thanks.
