Thirteen years in fact - so one would (rightly) assume that I've been happy with them. For me it's the personal service I get if I need to ring for some advice or to check something.
I would, however, say that I was a bit confounded when I called a few months ago to see what arrangements were envisaged for 2025 when the phone landlines are apparently going to be withdrawn by BT/Openreach. I did speak to a very knowledgable fella who, no doubt, had his finger on the pulse but it did seem a bit complicated for the likes of a simpleton such as I. As a domestic customer I haven't heard from IDNet in connection with the propesed changes and guess there's still plenty time but I'm hoping that for residential customers such as I it is made as simple and easy to understand as possible.
