Moving your tap point will bring your power levels back in spec for now but if there is noise on the network which gets fixed this week then your newly lowered tap point (depending on how low they have out you) may now take your power levels out of spec. The tech is correct in saying that if there was a problem a lot of customers would be ringing up complaining but they only know there is a problem when a tonne of calls get logged, it is circular reasoning. It takes a tech to come out to two or three of the same jobs in the same area to notice the fault and then he escalates it to networks to get fixed. Unfortunately not everyone is tech savvy and looks at their power levels to see what is wrong so these things don't always get picked up immediately.
