I bought a keyboard from a well known company about a year ago. It no longer works. So I arrange to send it back. (it's not quite a year so still in warranty) I have been told that the keyboard is now discontinued so they will refund me, but as the item is older than 6 months old, I won't get a full refund?!?!?! I paid £63 for the keyboard and getting £51 back. Are they allowed to do this??
