Hi CreavenDylan,
Thanks for your post and a big welcome to the Community. It's great having you on board with us although I am sorry to hear you're facing problems when trying to update your parental controls and gain access to your My VM account.
Let's have a look to see if there is anything registered at this end first. Once we have established that, we can look at what we need to do to resolve this.
In order to help further I will need to pass data protection with you. I have sent you a private message regarding this and will investigate further once I receive your reply. Just click on the little plum envelope at the top right-hand side of the page to access your inbox.
Thanks,
