I bought a couple of pairs of work trousers and they don't fit so I want to return them, of course I pay return postage. However on reading the terms and conditions on the bottom of the page it states that if the items were free delivery £2 per item will be deducted on refund, and returns will only be accepted on contacting the seller for a return code. Although it's not a lot of money I'm a bit miffed that they should be able to do this. Is this right? Or can I just open a dispute? Never had to do this before so any advice appreciated.
