Could be "the luck of the draw."
Three of my relatives use TT BB, two have had no problems and found the service to be very good and the third has had big problems and found the service to be very unsatisfactory.
If the TT internet connection is down, for what ever reason, then it can be very difficult to access the forums if one doesn't have a convenient, alternative internet connection. Phone support may or may not be good - "luck of the draw" again.
On the basis of a 66% success rate, among my relatives, think I would personally not use TT broadband.
Other ISP's are also not perfect but a least, for example, Plusnet will provide a free phone dialup number that one can use with a dialup modem to access the net even when an intermittent line fault ticket is raised.
