Thanks Ray but just spoke to BT and they say I would not qualify for any customer discounts (obviously) and they cannot guarantee to average 30mb speed or over. Also I'd have to enter a new 18 month contract.
VM are doing a 12 broadband only contract and by then the BT network problem here should be sorted and I can come back. I don't mind paying BT more for 60mb than VM charge for 100mb but not 35 to 40mb.
Far too old and fat to be riding very fast motorcycles...... but I do.
