I need to find out how to dispute an engineer call out charge of £129.99. We did all the checks that BT reccommend before booking an Openreach engineer and when the engineer did arrive he replaced the master socket. As I understand it that does not qualify for a call out charge (we had not damaged any equipment of wiring, neither inside the house nor outside). The engineer was very non-committal at the time over whether we would be charged or not, his words were 'I just do the work, not the billing.' HOw do I get a copy of his report and dispute this?
