Gotta admit, first touch with customer supports been ACTUALLY VERY GOOD.
Number ported from BT too, could call out, not getting calls in.
Gave em a ring, FIRST GUY TO ANSWER THE PHONE had me on with IP checks + looking at router settings (whatismyip etc) showed on a class D (185....) network, their statics are on 149... so eventually a missed step my side. Rebooted and let it pick up the correct IP, all good. Still wasn't calling in though.
Sat down a sec give it a moment, maybe some routing to update somewhere/etc and the phone rings...
Guy I was talking to from Be who'd done config tweaks etc and all now working + good.
That to me is pretty damn spotless in the current day/age. Might well have been a hideously lucky one off too but positive so far. Speeds seem fine too (920/840ish).
