Cancellation request

Hey everyone, again. Sorry to post another topic here, but when it comes to cancelling a service, things seem incredibly ambiguous. I recently posted something about processing cancellation request emails in which their scheduled date was left blank. Then I had an employee tell me it was simply due to backend issues and that my billing stop date however is set for the 3rd of September. Well it is now the 4th and haven't received any slight insight on whether everything is done now, I've returned my gateway as well. I know it takes time to process everything, but I want to assure my request indeed has went through. If any of you could help me out on this, I'd appreciate it!
