"Fastest" resolution is to phone up. But there is no "TV Go" option from the many choices presented to you. Whichever you choose, the automated system decides that, without even knowing what you are calling up about, resetting all your equipment is bound to solve it. So it won't even connect you to a real person, rather it will reset your equipment, (taking your TV & internet out of service quite unnecessarily) then ask you to call back if that doesn't solve the problem, which of course it won't. You call back, and hold while some distorted noise that is probably supposed to be music blares down the line The first person you speak to inevitably isn't able to help, so you are put on hold again for more earache. So when I say "fastest", I mean it could take up to an hour to resolve what should be a simple request, just to fix a problem that isn't even of your own making.
