Samsung refuse to refund Icon X Earphones

<p>I purchased the IconX from the Samsung store in Tygervalley on Friday the 25th.</p> <p> </p> <p>After getting home and testing it I have found it to be very dissappointung with regards to audio performance and the heart rate monitor not at all as expected.</p> <p> </p> <p>When I tried to return the product on Saturday the 26th, the store personnel told me that they do not refund earphones once it has been opened.</p> <p> </p> <p>How can Samsung refuse to refund a product when the users only method of assessing the product is by opening it and testing it??</p> <p> </p> <p>I want to return the product and refund it asap. As it isn't even a good audio product so it is totally useless to me.</p>
