don't mess about with your settings for a quick fix.
Maybe you should let your idiot tech support employees
know that as they seem to be the ones giving the advice
on changing settings and have no clue what the hell is
going on. BT sounds more and more like a mickey mouse
club all the time. Unfortunately, it seems to be the only
service a lot of people can get. It's sad.
I'm unfortunate enough to be sitting in my business tech support chair at BT now.
It seems that your
paying customers are the unfortunate ones.
