If the damage is not fixed until then, it would be 17 days since the properties had internet.

"We apologise to our affected customers in the area, and assure them we are doing everything possible to return services back to normal as quickly as possible," the spokesman said.

The customer said they were feeling "completely helpless" after repairs were pushed back a week.

He said Telstra had committed to offering compensation, but said it was becoming difficult to run the business remotely, or through internet dongles, for such a long period.

The Telstra Outage website confirms internet is down in the area and that it's expected to be fixed next Friday.
