I wanted an exchange for some trainers, they had the size online I wanted. However my money was returned as they said they did not have the size. went back to see if the shoes had been sold out, they were not! so I had to re order and pay again for delivery!! I don't understand that, and was very frustrated by this! your delivery charges should be free if we spend a certain amount! why did I have to pay double! when you had the correct size! and no free returns!!
