Forum contributors do not have access to Microsoft support tickets. If you were in contact with someone from support, you have to contact them again. For consumer (home use) products, the support chat is the starting point. Go to https://support.microsoft.com/contactus.
If you want to ask your peers in the forum, you can do so (too).
You'd have to explain what you are trying to do, of course.
Many billing questions can be dealt with on the web. If you sign in to your account at https://account.microsoft.com/services , you should be able to tell the status of your subscription, for example. You should also be able to turn off recurring billing and cancel the subscription, if that is what you are trying to do.
