I get as frustrated as anyone, but it’s not the fault of the person whose job it is to take my call.
I remember once on the phone with Comcast I just explained the situation and jokingly said look, if it helps, feel free to tell ‘em I’m yelling and screaming. The guy laughed. An engineer called me an hour later with a firmware update for my modem.
Sometimes there’s no winning. But sometimes it helps if you can put people on your team
It seems to ease the tension a bit, anyway.
