I don't see why clearing blocked ducts should be chargeable to a customer anyway, after all it's unlikely to be the customers fault that the ducts have become blocked.
When the OR survey was done the guy from OR said its not my fault there is no ducting laid between my property and the AGnode and I should not need to pay for that as that is what OR are required to provide for customers.
But my charge was for me to pay for it all for my estate to have new ducting laid.
Hence why I refused. What should be and seems right is not what occurs with FTTP on demand with OR.
