Hope this is not tempting fate, but after the terrible talktalk service DST seems like nirvana!
Telephone helpline is first class, sometimes a small wait to get through, but the staff are very helpful and really know their onions.
Installation from CD is quick and simple, even for a newcomer to broadband. I have only given 6 for speed since I am at extreme range from exchange and was warned in advance that I could not expect any high speeds, so I can only say that jumping from 30kbps to around 550 seems like lightening to me!
Price for package of line rental, unlimited calls 24/7 and broadband is very reasonable. So far so good!
