Telstra distributor, ICT123, has blamed the 'fraudulent actions of one isolated dealer' after it was forced to close last week.
The Melbourne-based distributor, which is a supplier for about 1000 Telstra dealers, sent a Dealer Alert to customers advising of the news on Thursday, April 24.
"It it with deep regret, that we hereby advise ICT123 Pty Ltd has ceased trading," the letter said.
"Unfortunately, after more than seven years building our business, a series of events including the fraudulent actions of one isolated dealer has put our business in jeopardy."
It said the board of ICT123 was in discussions with legal advisers and that it anticipated a further update within 48 hours.
“Clearly, many unanswered questions remain, however we ask for your patience and understanding in this difficult time,” it said.
A spokesperson for Telstra said the company was working with ICT123 to explore alternatives for their partners to ensure all of their customers have access to Telstra services.
ICT123 has closed its dealer support centre and is not processing any further connections.
The Australian Securities and Investments Commission website does not have a record of the appointment of any administrators or receivers to ICT123 at this stage.
ICT123's vendors included Acer, Apple, HTC, LG, Microsoft, NetComm, ZTE and Samsung.
The company reported a $669,000 loss in 2013 after recording revenues of $6.2 million.
