20/12 Branksome Another BT walk away from a job. They tested to there master socket and was happy there bit was working ok so i tested the customer wiring fault found on an external run. Rerouted cable and put joint in to cut out the damaged run of cable. Tested internet 1mhg down SNR was up at 29 (noise margin in picture) spent nearly 50min on the phone to EE on behalf of the customer to get a reset done. That should have been a 15min call but the girl on the end of the phone did not have a clue asking the most stupid questions must have just been a screen reader asking the questions. After the call re tested internet SNR back to 6 speed upto 19mhg another happy customer. BT should have said about the SNR reset and the problem on the line could cause a problem with the internet but no advice or warning from them.
