Yes I have had problems, but BT have always resolved them. I have faith in their abilities.
I have: BT Business Broadband. No problems in 4 years, apart from some billing issues, which we sorted with 1 phonecall. If you renew they do tend to bill you for 3 years in advance again!
BT Vision - great system which is exceptional value (pay around £12) - each renewal date they have dropped price. Some issues when I moved house, but their phone support was efficient.
BT home landline - some issues moving in, but engineer sent to resolve. Some ongoing issues - broadband cuts out with the ending of a phonecall. WHen I get round to it, I will speak to BT, and I have confidence they will resolve it for me.
