Hi,
So I can better assist you, could you provide more details about the subscription you are trying to cancel? If this is in relation to your Google Ads account, I would recommend that you reach out to the product experts via the
Google Ads Community Forum as they should be able to provide guidance regarding this matter.
Thanks and regards,
Peter
