No Response To Cancellation Request

Since the 24th of January I have been trying to cancel all of my Subscription Services and give my 30 days notice but I have not received a response. On the 24th of January I sent an email with my cancellation request as well as a copy of my ID to [Email Removed] and stated that my 30 days notice should start from the date of the email. However, I still have not received a reply. On the 30th of January I phoned 10210 but was on hold for too long so I hung up. The same day I then emailed [Email Removed] with my cancellation request and attached a copy of my ID, but I have not received a reply. Then yesterday I sent another email to [Email Removed] asking why they haven't rep**** and I'm still waiting for a reply. I just want confirmation that my request to cancel all of my subscription services was received and that the 30 days notice period started on the 24th of January when I sent the first email.
