Within 10 hours of posting a report on a Harrison family's disappointment with Telstra's NBN connection service Fairfax had been told of eight more cases where there had been delays with either the installation of the NBN infrastructure to the home, the connection of NBN services through Telstra or one of the other authorised service providers or both.

''We live in new Macgregor and got our connection to the NBN through iiNet about three or four months ago,'' Annie Wyer said.

''We've found the connection box inside the house fails every month, losing our connection to the internet. We rang them the first time it happened (just as well we have mobile phones) and they guided us so we had it up and running again pretty quickly.

''As it has happened more times since then we wonder whether we should get them to come out and replace the box. [But] our experience with telcos has left us with a very cautious attitude regarding their service provision so we've decided to do nothing and just reset it every time it happens.''

Ms Wyer said the family had gone with iiNet because of previous bad experiences with Telstra. ''I've found that if you want proper service [from Telstra] you need to pay a private Telstra contractor to do the work properly.

''They are the real experts. They all left the organisation and set up their own businesses.''

Annoyed, of Amaroo, reported having to hold for an hour after calling Telstra to reschedule an appointment.

''Telstra know that if you want good coverage Australia-wide you are going to go with them. They think they have it in the bag but their customer service is woeful.''

Imms, of Ngunnawal, said that after waiting almost five weeks for an NBN connection a rep finally revealed the original application had not been processed.

Frustrated, of Harrison, confirmed Telstra's advice to Fairfax that the sheer volume of connections being sought was contributing to the delays. It's not just Telstra's problem however. ''We have been advised that there is a 'capacity constraint' with all NBN installations in the ACT and that recently NBN Co civil contractors had had contracts cancelled.''

Not all of the feedback has been negative with J72, of Ngunnawal, saying that although Telstra's NBN service cost an extra $24 for the 25-megabits-per-second plan it left the ADSL2 service ''for dead''. ''And my installation was done and dusted in under two weeks.''

The Department of Broadband, Communications and the Digital Economy said the NBN rollout was a work in progress.

''NBN Co and its contractors work closely to investigate any issues that arise,'' a spokeswoman said.
