I can see what's happened here and please accept our apologies.
Line rental hasn't been charged, but the contract hasn't been added so the broadband discounts have not been applied. This was an issue on our side as the ticket for this to be actioned was closed. I can't add the new discount until the original contract has expired but I'll process all refunds due now. I'm also creating a 'ticket' on your account so that I can monitor for you.
