Thanks for the answers.
My friend has tried to contact pandawill, but he has not yet received a reply.
I think that the option for sending a replacement screen is the best option, because like AnimaTechnica said, returning the tablet from Belgium to china is rather expensive.
I will report when more info is known.
If no reply comes in quick, I think it will be best to try the option gurgle mentioned.
If it was shipped UPS or FedEx you may be able to file a claim with them. It's a lengthy process though. Contact the vendor first to give them first shot at fixing the problem. You should not have to pay for shipping to return it or for your new device.
Exactly how broken is it? Is it smashed cracked split ? what was the packing like? If the packing was flimsy then the carrier is at fault.
How do you prove you didn't do it? Get pandawill on the phone and talk to some-one - be nice.
Well it's not the screen itself that is broken, but the cover. First the glass of the cover was scattered, second time it was a split. With the second glas it is workable, but not nice.
It is almost unbelievable that it got broken because the packaging was very good.
Pandawill promised to send a new one again.
