Hello,
Sorry to hear you are having issues. Not really sure what you're requesting to cancel. If it something to do with your account. Perhaps, it is best to raise support ticket using the link below, use the "Ask a Question" option. Include all information details. Remember to record down the ticket number for future reference if needed. Do not raise multiple ticket, that will make your ticket back to the end of the line. Send once and wait. Ticket will be answer by the order they send in.
