Should retail send what was in Order description even if an error?

so i googled a perfume and found Harvey Nicks selling it for £120 for 75ml (which i think was an error as it seemed cheap!) so i jumped on it and ordered.. now the item is unavailable to order at all..but still listed with the same info. Theres a second listing for the same item for like £235.

my klarna confirmation says 30ml. But my order confirmation and dispatch all say 75ml.

If they send me 30ml i’m assuming they either need to -

offer a free return cause i wanted 75ml

or honour that price for the 75ml?
