No, because I’ve worked in support and know that that’s a fast-track to really bad service.
OT, but this seemed to work for me dealing with Three. 2 1/2 months of being told ‘your sim card will work in 48 hours’ and ‘noone can deal with that until 9am tomorrow, sorry’ culminated in a tirade that would have made a merchant seaman blush. Despite it taking both 48h, and not being able to happen until 9am tomorrow, I had a working phone half an hour after that rather one-sided conversation.
I only hope the poor sod who copped it on the phone passed it on to who it was meant for, but then as he wouldn’t put me through to his manager, I think he deserved it…
