My property is supplied via overhead cable, but the section between the green box and the overhead pole outside my house is probably in ducting pipe, and approx 100 metres long, I would of thought that it should'nt need to have the tarmac path dug up. The engineer who told me about the fault said he had more or less pinpointed it, and I even remember him saying he was going to mark it out if he was called out again, but I have always had other engineers come every time i get them out since.
Thanks very much for your help.
I will get back on to live chat tomoorw.
I did have an engineer booked for this Tuesday.
But BT text me to yesterday......"we have checked your broadband and now it is working correctly, we have cancelled the engineer booking"
