A LAUNCESTON business has questioned its options for expansion after signing up to the National Broadband Network.
Brisbane Street's Inerva Enterprise Software was connected to a fibre-optic service in September last year - one that lasted about four weeks.
The company has been forced to operate a three-line call centre on back-up ADSL lines since October.
Inerva software designer Travis Purdy said despite repeated contact with NBN Co and service provider Internode, they were still left without a solution.
``All we've been handed is a bunch of dates,'' Mr Purdy said.
``Lately they've told us they'll know more after June 5, not when it will be fixed.''
He said responsibility for the issue was continually handballed between the two companies.
Mr Purdy said the company spent more than $20,000 rewiring its building to best utilise the new fibre-optic connection, only to be relying on copper.
Inerva's Carolyn Frichot said the company was ``poised for expansion'', but could not move without a reliable connection.
An Internode spokesman said repeated advocacy of the case had been put to NBN Co, but it was still waiting for a resolution.
``NBN Co has told Internode that it has scheduled a technician to deal with this issue at the Inerva office on June 5,'' the spokesman said.
``This situation once again highlights the need for NBN Co to improve its systems for handling and promptly resolving problems raised by retail service providers such as Internode so customers are not left with long delays to get the NBN service they are seeking.''
