Rs.19000/- is not a negligible amount. Sorry to hear that. Anyupdate? Did the seller protection compensate you?
I completely understand your concern. At the same time, I'm a buyer on ebay(I never sold anything) and have faced some problems with deliveries. I'm mentioning these here not to support your buyer, but only to say that there will be genuine claims too.
1. I bought an 3 items from china(or hongkong do not remember) from different sellers. Two were received, and one was never received. When a claim was raised, seller said that he will find out from his courier company and will track. Probably he could not get any information, he cancelled the transaction and refunded. It was smooth. He was a seller with very high positive feedback.
2. I received a blank package with a few folded empty papers from a diary instead of a mobile pouch. Here the package was intact and there were no signs of tampering. When I raised a claim, seller asked me to send back what I received to get a replacement. This pouch was around Rs.200 and as a buyer for whom courier is not a regular thing, the value finding a courier office, courier cost, fuel cost and time involved will be more than Rs.200. I thought its better to leave it as that than doing all that and also sent the same email to seller. But seller has shipped a replacement. This was on ebay india and again seller was with 100% positive feedback with I think more than 500 or 600 ratings. Here I suspect a negligence or sellers staff rather than the seller himself.
3. I bought a hard case for phone around two weeks back. I received the package and realised that it was tampered. I was not sure if the case was going to be inside or not. Luckily it was there. From the packing, it was clear that it was opened and pinned and taped again. But I probably received the item was not useful for whoever opened the item.
4. I bought a used mobile phone two weeks back. Seller sent the phone and everything as described, but the phone has an issue. The phone drains battery in around 12 hours even without any calls. Put a new battery or anything, it just drains, this is not a battery problem but the phones problem. Seller has hidden this issue before sending and now says that there was no issue and I tampered the phone. I opened a claim yesterday and it is pending, I'm not sure how it goes I received the item, but the problem is the phone has a major issue which was not disclosed by seller.
I'm not supporting your buyer, but just saying there could be genuine claims too. I account most of these to the courier or postal services in India rather than either a seller or buyer. Everyone might have atleast one instance of loss of things in couriers/posts or even airline baggages.
I've been happy with ebay so far, but the latest issue I'm facing(phone) made me decide that I'll not buy a high value item again. Because of this, I'm loosing mental peace and time. I will only buy low value items which I can ignore even if I do not receive.
