Sadly, 2 years on, I have a similar issue with the same seller as you Waltesfalcon. I purchased a Tissot PR516 described in excellent condition, and serviced 1 year ago. Paid AU$527 through PayPal.
After a 4 week shipment period from Argentina, the watch arrived. The internal movement was loose inside the case, and the hour hand was totally misaligned with the minute hand (on the hour). Immediately I contacted the seller and he asked if I could get a quote to repair it locally. The cost locally was too high and he offered $100 compensation or full refund. I opted for a full refund. All this communication was made through Ebay (Money Back Guarantee).
This is an important part of the process that all buyers should follow. He sent me a return UPS label which did not work and consequently sent me another label.
This part of the process took longer than it needed to be because of weekends involved and public holidays in Argentina. Four days after the parcel was picked up from my home, I received a call from a UPS co-ordinator from Tullamarine airport asking for a commercial invoice. Therefore, I know for a fact that it was in the UPS system.
I allowed another 4 weeks for transit to Argentina. After this time elapsed, I contacted the seller. He had not yet received the shipment. I immediately contacted UPS. They could not find the shipment and the tracking number showed up nothing. I then made a claim for the lost parcel. UPS said they would get back to me in 5 to 10 business days. I heard nothing from them. I contacted UPS and was told that the case was rectified several days ago. However, I was never told this. Adding insult to injury, they said that the claim could only be made by the seller, as he had organised the return label. I gave the relevant information back to the seller. I allowed a few days to pass before contacting the seller. I had contacted him 3 times over 3 days with no response.
Time to contact Ebay. Stupidly, I let this go too long before escalation. They have a “Platform of Time” in which to escalate. There was no way they were going to change their mind. I messaged them, contacted them by phone, they didn’t budge. I then tried with PayPal via an email address I found. I gave a detailed account of the situation. They refused to budge on a refund. So far I had tried UPS, Ebay, Paypal, all no resolution. In desperation I put the details into a note, dare I say, to ChatGP. The result was an exceptional upgrade to my notes. Amazing. I then sent this to an online agent on Ebay. Within 15minutes the situation changed. The case was opened and closed in my favour. I was refunded the full amount.
The reason for this long winded description is based upon my personal experience over 3 months from start to finish, for any future purchases you should closely follow the “Platform” rules of Ebay and PayPal. If done in time, the results are quicker, and usually in your favour. As for couriers, it is most important that you have copies of all documents and proof of pick up. Also check the tracking numbers a few days after pickup to ensure it is working. If not working contact the courier and send the same information to Ebay. Always keep your emails and proof of any communication between the seller and yourself.
The critical wording in my case was as follows….
We have reviewed the transaction details for you and can see that you've done your part in the return process by shipping back the item, since it was a faulty item the return label is the seller's responsibility and here the seller has to resolve this issue with their shipping company.
I hope that this information may be useful for anyone caught up with a similar situation.
