A TELSTRA customer is frustrated after an NBN installation has left him without access to the internet and a shoddy land line.

Ron Hutchinson, 76, lives at The Lakes Retirement Village with his wife and said he has had no internet access since Friday, January 8, when a technician came out to install the NBN.

"We don't have the internet and we use the internet to contact relatives overseas," he said.

"When I make phone calls there is a lot of static and crossed lines because I'm hearing other conversations.

"This all started on January 8."

Soon after, Mr Hutchinson said he received an email from Telstra saying a technician had been booked for January 11 between 1pm and 5pm but he claims nobody turned up.

"We rang Telstra and were told that they were very busy and couldn't come out until February," he said.

A Telstra spokesman apologised to Mr Hutchinson for the delay with connecting his NBN service and said it was scheduled to be completed for early next week.

"NBN installations frequently require two appointments - one with NBNCo to install their infrastructure and the other with the customer's service provider," he said.

"The required appointments are confirmed with customers as part of the activation process."
