Hi Pamela,
I am in the UK where we do not have many (if any) places to buy wool, so I always shop in the US.... Try the Dorr Wool Store... they are amazing... when I order now (I have to email them because I pay with a UK card), they ship my order even before sending the final bill for payment... Amazing Service!
I too would not be happy with that response, I would contact them again to let them know that as you would like a refund. Does the site mentions that sizes are approximate? Do they state that the could be 1.5" shorter than advertised?
Anyway, I hope I have helped a little.
Hugs
Caroline
