I believe that he did actually help you get your funds back. I hope you understand the reason you're getting all these questions is because you're the only person that appears even a little credible that has come forward and said GP actually returned your funds. He's been here over 3 years. Almost 5,000 posts. And you're the only one. (Of course it's pretty clear he managed to scam you out of ~$1k USD a few months later, which ironically makes you even more credible, but that's besides the point)
My guess is that your case was one of the rare ones where a few emails was all it took to convince the Casino to return the funds. I wouldn't be surprised if he tried to appear to you as if he was using a lawyer and working with multiple people, but really it was just him trying to scare the Casino into giving you a refund, and it actually worked for once.
Did he ever have other players contact you as a reference?
Did you know the Lady that you decided to put up the money for personally? Or did Game-Protect introduce you guys and then help work out a deal so that "everyone could win?"
To be clear, I'm purely speculating here.
He did use a lawyer with my case but the case did not take too long to be settled. Nonetheless, I did try SBR, CasinoMeister, AskGamblers and no one helped me with the case - in the AskGamblers website I even spoke directly to the bookmaker who just ignored my claims - so GameProtect was helpful in getting this resolved ... prior to it I've also contacted some lawyers in Curacao myself and no one was willing to help or was but with a high cost - so GP's resolution was cost effective and it was effective as well.
Now - moving forward - I have no idea how this thread turned into something else, something that if I had to see this thread now - I would probably avoid dealing with GP because of all the warnings and negativity here, and I see him fighting the claims that you're raising against him ... I also think that he should settle the issue with h4ns in some way - just reach a settlement, I am huge believer in compromise and in doing the right thing.
I don't know where this is all going from here, I feel bad for all sides - I think GameProtect is genuinely trying to offer a genuine service, but on the same time he cannot have an open dispute with another user and leave it like that - besides h4ns' case there is the only other case of Jenni here, but she hasn't given any update here and I'm not sure if she would feel comfortable doing so because she is not looking to be attacked. Asking questions is fine, attacking isn't.
He never used me as a reference for other users for direct contact, everything was posted here so he could point whoever he wants to the thread here, I didn't know Jenni in advance, it was the latter option you described just without an introduction initially - I chose to invest in her case but it looks like her case is more complicated than mine - she used a casino website where the owners have simply left the company and cannot be reached, I don't know what will happen from here, the only thing I can say is that h4ns in my opinion should be paid or at least GP and him should agree on something, and in regards to Jenni's case - I have no idea what will happen with it ... If you're asking if I would go ahead and invest in another case - probably not, because the investment hasn't proven itself - but I took it as an investment with some risks involved and known in advance, so I don't accuse GP of any wrongdoing .... in fact I think all the red flags and the huge amount of negativity that he gets - is in some way unfair - I still gave him a positive feedback and I haven't changed it because I stand behind what I had experienced in general - however if the h4ns' case won't get resolved I'd get upset - why? it's not even my case, but as I said I believe in justice and in doing the right thing. That's why I also called GP to settle this with h4ns. Just get it settled, the amount is not huge neither.
In regards to Jenni - I am happy with whatever happens, I still won't accuse GP for any wrongdoing here - but those who do so with a click of a button should really bring some more credible evidence into the table - otherwise why is he getting so much negativity if the only 2 "pending" cases are h4ns and Jenni's? It doesn't make any sense, by all means this is equal to so many red flags - UNLESS - the issue with h4ns won't get resolved, and I do agree this MUST be resolved, it cannot stay like this. If GP doesn't understand he needs to SETTLE things with h4ns then I'd truly feel sorry for his business - and this is a case I am not even involved with, but for the sake of your business, GP, you must SETTLE with h4ns - otherwise you're just shooting yourself here in the leg.
