Hi there,

I can see that your new contract hasn't gone through yet because the product change to fibre extra is still pending in our supplier systems. That's due to happen on 10.08.022 so all being all your new contract and pricing will begin from then. This means that your next bill in September will have more discounts than normal to reflect this.
