disgusted!

I bought a bra from the website and as these things are hard to buy online I first checked their returns policy which stated as you would expect that some items can't be returned for hygiene reasons. It then listed examples such as toiletries and items which you would insert into the body. ..fair enough! It also mentioned that we understand some items are not suitable, wrong size etc and appeared that refunds or exchanges would be possible in such cases. I bought the bra and when it was received I saw from the pack it was not going to be the right size so contacted them to exchange it. I'm now told they won't for hygiene reasons!? It's a bra...you can try them on and exchange or return in any high st store. I did remove the item from the packet but I have not had to break a seal to do so. I would expect that if this item was non refundable it should have been listed in the returns policy or made clear on the order page as this is a very unusual policy for a bra. I'm now left having paid for something in good faith which is entirely useless to me. I am disgusted and feel completely conned by this company. I will make sure to post as many bad reviews as possible to warn others and tell all my friends not to use this website!
