BTCare picked this up and resolved the issue very quickly.
New Humax box
New HH5 both Free of charge.
So I thought until I got my BT bill. They had charged me for the HH5 and delivery.
The net result of the original one off charges is my DD has doubled!
I had a call today with them and after being on hold for 25mins they refunded the HH5 cost but not the delivery and couldnt change the DD as the 'system' wouldnt allow it.
I wish I had stayed with Sky.
