There's a narrative from the forum about newbies especially when it has to do with matters that requires trust and some form of reputation. Just like this wallet recovery service you're in search of for reasons best known to you. I will advise you be careful with how you can about it in engaging with those behind the listed thread you found from your search claiming to offer the wallet recovery service.

They could be genuine but their lack of reputation in the forum necessitates that you thread with caution and also demand to see previous cases of your type they have successfully resolved. Perhaps that can help build your trust for a start.
