More than half (52%) of those who complained were not happy with the response received.
William McCausland, chairman of the Private Hire Proprietors Association, said as far as his company was concerned any complaints were thoroughly investigated and appropriate action taken.
"Road conditions, traffic conditions and time it takes can affect the fare, so really you need to use the taxi metre and it will determine the fare. An estimate can be given," he said.
He said passengers should always use a reputable taxi company where "you will have some comeback if there is a problem".
The General Consumer Council believes that the review of the taxi industry should result in better service, more legal operators, improved consumer protection and awareness, and a framework for competitive and reasonable fares.
The council is an independent organisation which campaigns for high standards of service and protection and a fair deal for all.
