The OCEs really are very helpful.. I had my service transferred to a new home last Thursday.. The phone was fine but the BB didn't want to play ball. The Kelly's chap who visited told me that it would take up to midnight to go live but it didn't.. I contacted the TT forum and it was sorted by Monday. It seems my BB was 'parked' in some way.
I agree, we recently had an intermittent problem with wi-fi which would kick us out of gaming and cause internet problems etc (ethernet was fine so it wasn't the connection) i requested a replacement router to see if it was the router that was at fault and once the OCE answered 2 days later a new router arrived the next day.
Its a shame they couldn't make it 24/7 support as i find typing and reading their replies a lot less frustrating than trying to understand a foreign accent and i always feel sorry for the poor customer service rep trying to understand my Cumbrian accent coming back at them.
One thing i would suggest if you decide to give the forum a try put as much detail in the first post as you can if they have to keep asking more questions it prolongs the fix,
Good luck and keep us posted.
