I bought something of ebay , its from a business and the item doesn't work, it shows up in my pc but there isn't any space to use, now they don't seem to want to send me a new one out and instead have told me they'll refund me..... half of what the item costs, I told them to go ..... not a chance, inaway I contacted ebay about this, I want to just go to argos and buy one instead so am I within my rights to demand my money back instead of him trying to send another out ?
