Simply file a dispute which Is handled through PayPal's Resolution Center, and then escalate It to a claim. PayPal will then take over and decide whether to accept or decline the claim.

If that fails, perform a chargeback through your credit card provider, or a bank reversal via your (bank) merchant.
PayPal should always be used when all else fails, so have you exhausted all methods to no avail?

Thanks for the reply. On PayPal do I claim for a DNA, will currys not put up tracking?

Has anyone done a successful claim with currys?

DNA is risky in that if they do provide a tracking number you've basically lost. You can only open a dispute for a transaction once unless you hassle the (currently hard-to-reach) customer support.
