Vocus-owned Dodo, iPrimus, and Commander have become the latest in the string of National Broadband Network (NBN) retailers asked to compensate customers for not providing them with the speeds they were paying for between October 2015 and June 2017.

In total, 1,912 iPrimus customers, 3,384 Dodo customers, and 565 Commander customers will be offered remedies, including moving to a lower-speed plan with a refund, or exiting their plan with a refund and no fees.

During this time, the Australian Competition and Consumer Commission (ACCC) said iPrimus advertised its highest-tier plan as "Download speed: Up to 100Mbps. Upload speed: Up to 40Mbps. 100/40Mbps is as fast as you can get and will surely feed your need for speed".

From its 25/5Mbps FttN customers, 901 could not reach those speeds and 115 could not reach 12/1Mbps; and of its 12/1Mbps FttN customers, 92 could not reach those speeds.

Of iPrimus' fibre-to-the-basement (FttB) customers on the 100/40Mbps speed tier, 14 could not reach those speeds; and one of its 25/5Mbps customers could not even reach 12/1Mbps.

Dodo's undertaking [PDF][2], meanwhile, shows a total of 70 percent or 2,436 of 100/40Mbps FttN customers unable to attain these speeds, with 1,037 of these also unable to reach
