Cancelling Trial

Hello, my trial is expiring tomorrow. I went to cancel my subscription, but I need a reference number and don’t have any email with that number, to access my account. I can’t remember if I entered billing details and it doesn’t look like there is a direct way to communicate with ccleaner about this issue. Does anyone have advice on the best way to cancel?
