Componants don't work??

[McNultyyy]

Just talked to them today, and they said they can't figure out the problem so im going to have to send it back.
But the thing is I have to pay for postage when they were the ones that messed up. Does that not seem wrong in anyway?

EDIT:

Just had a look at trading standards, and I won't have to pay for postage as the item is faulty.
