Curtains do not match

[BigAllyMac]

My wife purchased two voile net curtains from Harry Corry Interiors. Each was individually wrapped with identical material and pattern descriptions, and the same item barcode. Through what transparent wrapping there was, they appeared identical.

 

She unwrapped them to shorten them to fit one at a time and it was only when she went to hang the two shortened nets that it was clear the material and pattern on each was different.

 

She took them back to the shop, who told her that (a) she should have spotted the difference before altering them. and (b) to a notice advising that they would not refund curtains if the materials were found not to match after they had been taken from the shop. As a "favour" they replaced one of the pair with a new one of the correct material for a charge of £5.00

 

I content that she is entitiled to a free of charge replacement under the Sale of Goods Act as one or other of the curtains was not as described, i.e. pattern name and code. In this context, the notice I referred to is surely meaningless as in effect what it says is "we do not honour your legal rights".

 

Can anyone help with this one - is my understanding of our rights correct?
