Ok I will get reading. Do I have a time limit before I can make a claim?

Thanks for all the help. Do you have any suggestions on which one to read? There are many and I don't know which is relevant. Is the small claims post still relevant? It was made in 2013 so just want to check.

I put £600 in the box on their website when paying for the postage.

They sent me £100 on the 11/03/2021. The incident happened on 07/02/21. I'll try to say it in value rather than items. I sent him £460(GPU1), he sent me £360(GPU2) + £100 to make up the difference. He ended up with no £460 in the box, So I gave him his £100 back plus £360 in cash instead. I'm out £360 in effect as I was paying with an item rather than cash. All in all they've stolen a £600 graphics card so they owe me the maximum no matter how you look at it.

Hi BankFodder/Andyorch, Thanks I'll look into those other posts! I put on the website that it was worth £600 when I paid for postage. We have photographs of the package after it arrived, I have a picture of my box with my reddit username and date on, and we have photographs of the curtains. I would have expected foul play from the person receiving but given that he sent me his own card (which I'm still using), I believe him. We've talked loads on WhatsApp and both tried our best to get the police involved, messaging the CEO etc, but to no avail. I paid him for his graphics card (£360) and refunded the £100 he sent me, so I'm £360 down. I got no say in accepting or rejecting their compensation, they just sent it to me on Paypal and told me the case was closed, scummy.

Hi All, I've just found these forums and hope you can help. First of all I'll say I'll never use Hermes again in my life, what utter shite. So I wanted to swap my graphics card for a gaming one about 6 weeks ago. I had a Radeon VII, worth £590 at rrp, now going for £1000+ because of the shortages across the globe. I was experiencing compatibility issues, so I wanted to swap it for it's little brother, a 5700 XT worth about £450 rrp, now going for £500-800 on Ebay. I found a guy on Reddit who was selling his and I offered a swap. I didn't want to sell and then have to look for a new one so a swap was Ideal. He was skeptical of me as my card was worth more than his but I just wanted stability for gaming, not a compute beast that was power hungry. We agreed that he would pay me £100 on top of the swap to make it fair. We both sent our packages with Hermes with next day delivery, insured to the max (£300). His graphics card took 4 days to arrive with me as it was an awkward time before the weekend, mine arrived on a Saturday with him. The box had been tampered with and the graphics card removed, replaced with a set of brand new curtains worth about £90. I was and still am devastated. Hermes took 6 weeks to resolve the issue and decided that I'm only owed £100 as that was the PayPal transaction amount, despite being paid in goods, not purely money. They have failed to acknowledge that they lost an item now worth £1k, and closed the claim really smugly. I want to take them to small claims, but I'm unsure who to do it "to". Do you guys have any advice and details of what I should do next? Ideally I'd Oh flip them for the full amount but I appreciate their terms have been agreed to and an amount of £300 is their maximum.
