I spent one year of hell with IDNet, trying to get them to fix the constant problems with our line. The support guy, who I got to know quite well, asked me to buy two new routers and told me that slow downs were a "part of the TCP/IP protocol and to be expected". IDNet appeared to be simply reselling a BT connection and so always claimed that they needed to get BT in, and warned me that it would cost hundreds. Broadband was unusable at weekends and youtube videos would not download. The support guy would simply not believe this.

We switched to BT from IDNet. Since then we have had very very fast, glitch free internet.
