Well you learn something new every day
I've also had good experience from OR, twice an engineer has spent most of the day (about 5 hours) trying to sort my line out. There was only the one who was like "LTOK, gone" one of the times the line dropped as he was doing the test, probably the best time it could have happened
Shame they can't clone one or two of the OR engineers I have had here, they had real dedication to the work, not like few younger ones who gave up finding a solution to the continuing problems I had.
Last year OR engineer came to do line tests, line dropped while he was here, & he then spent 2 days here sorting out numerous faults he kept finding, & fixed them one by one on my line, including some network rearrangement work to get me the speed that dsl checker had estimated.
