Hi @Tim46,
Thanks for taking the time to post up on our Community.
I am sorry to see that your discount disappeared. Adding the HD add on should not have touched your discount.
The discount is coupled with your package and the contract for that. I'm happy to look into this for you but please note that it will take 5 working days before my team can pick it up for you. I'll send you a private message you can reply to us.
Thank you
DanielS
