Hi stu202202202,
Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums. ⭐
We're sorry to hear you've been charged more than what was expected. After you've made changes to your account, your first bill after the change will likely be a bit higher. This is because we charge in advance for the services. You would have been charged for the time the service went live, plus your usual month in advance.
Your bill will show the dates you're charged from via My VM here.
Future bills should match the monthly price that was laid out in your pre-contract documents, which would have been sent at the time of the change.
Let us know if you have any further queries or questions.
Many thanks,
