I find the idea of a company profiting from its faults calls pretty offensive.
Even more so when they also own a phone network, so most of the freephone calls cost them absolutely nothing.
This is after they've persuaded their customers to take a supposed "calls inclusive" package, but these calls are excluded from the inclusive calls. Appalling.
Sounds like the sort of thing that will get them on Watchdog.
Who's going to post the equivalent geographic code? If there isn't one then lots of direct extension numbers would be good, just to annoy them

Just the bunch of desks that end up taking the calls.
Any chance a list of numbers could be published somewhere prominent on this site?
