If the OP service is so bad, try a letter to the BT Chairman. He had his fixed by BT and he was miles from both a cabinet and an exchange. Seriously, letters to BT CEO have worked for me. I have no idea why some connections by BT are telephone poles, and others are underground. Ours is underground, but near neighbours is telephone pole. Since ADSL2+ went in at our exchange, speed has improved. I'm not sure that I'll go for infinity,altho Mr Mouse's number is impressive, and Mr/s Mouse mustn't be far away from me.
