Hi NJ10
The consumer does not have any rights when they change their mind about goods which they have purchased.
Often, the retailer, as a goodwill gesture, will offer to accept goods back and will offer a credit note or a refund. But this is entirely at their discretion.
Is it possible for you to go to the retailer and speak to the manager/owner directly? Face-face interaction often works well and you can clearly explain why you are returning it.
Failing this, I suggest that you ring again and ask to speak to the manager/owner. Explain that you would be willing take a credit note and pay for the delivery of the suite to be returned by their carrier.
Other than this, you really have no comeback unfortunately. Sorry!
I forgot to mention that there is one exception to the above. If you purchased the furniture from home - by mail order, phone, internet etc you would be entitled to a 7 working days' cooling-off period from the day that the furniture was delived to your home. If this is the case act quickly!
