GREYHOUND is to refund customers cash which the company was deemed to have charged them 'unfairly', following an investigation by the National Consumer Agency (NCA).
The waste-collection company has also promised to return customers' credit balances which householders forfeited until now, if they cancelled their contract within 12 months.
Following an investigation, the NCA considered a number of terms and conditions which Greyhound were imposing on households to be "unfair".
These included customers having to forfeit any credit balances if they cancelled their contract within 12 months and the charging of a €45 fee in the same circumstances.
Any consumers who paid these charges will now be refunded by Greyhound.
The NCA investigation was prompted after the consumer watchdog received 265 calls from consumers on a wide range of contractual issues concerning Greyhound.
NCA acting chief executive Sean Murphy said that during the course of the review they looked at a number of issues.
"We identified a number of contract terms that we consider to be unfair to consumers," he said.
"Therefore, following discussions with Greyhound, we have now reached agreement that these terms will be amended by January 18, 2013."
A spokesman for Greyhound was unable to say when customers who had been unfairly charged would be reimbursed.
In a brief statement, the company said it was committed to completing the process of reviewing its terms and conditions by January 18.
