trading standards or is this legit?

OK SO we went to a shop that sells bathroom sinks washes cabinets etc, they have no display only a catalogue u buy from. so once bought the label on THE BOX says

plese mke sure the size on the box is correct that u have ordered, once thebox is opened the product cannot be returned if incorrect size installation is acceptance of quality.

is this allowed? we bought it but now thy wont let us return. they did not mention this in the shop before buying only written on box ONCE BOUGHT

what can be done?
thereis no refund policy on the manufacturer website Genesis eden bathroom

they have a massive disclaimer taking away liabilty

How awful!

Re: trading standards or is this legit?

If u could not see the box BEFORE purchase you have a case. Take them to small claims court.

By the way, trading is overrated. Buy and hold works for the most part.

Re: trading standards or is this legit?

it sounds like once the box has been opened it cannot be returned…but if the box is unopened and the size is not what you want then it can be returned.
did you open the box yet?
