Paypal claims never hurt, as they tend to get the retailer’s attention at the very least.
Thing is that I don’t think it’s GBs fault, more the chinese postal service, not sure it would help :S
I decided to sell mine, instead of return it for the TN panel. In the past, I’ve had issues with items get stuck in Chinese customs taking weeks to reach the retailer. Best of luck!
Yeah I actually put up an ad for selling it on a local pc site but didn’t manage to get any replies, so I decided to send it back instead.
