Always been a bit of a problem with ADSL that when something goes wrong which is outside of the norm or (script) then support struggle, Plusnet used to escalate these issues to the more technically proficient staff to handle as often the issues are at the customers end or need a BT engineer visit, I guess as they've grown though these folks are overwhelmed or no longer have enough with the required experience.
Unfortunately my most recent experience is weeks of waiting, testing and providing information and still no help, replies saying everything is fine without reading the actual issue raised appears to be the norm and promises of a response fail to deliver.
Disappointing that it appears I'll have to move to another provider to get help or wait for the fibre rollout to naturally fix any exchange problems.
