If they lie about one thing, how can they expect us to believe them when they say another.
We only have the rep's word for it that Hello and Fenix are totally separate, everything else points to a connection of some sort. I would say that the same gambling licence is a BIG connection, and the same support staff is yet another significant connection. The differences can be explained away by having each skin target different market sectors with different promotions and managerial approaches, each with a significant degree of independence, but they all rely on the top of the pyramid to keep them viable, chop this off, and the separate skins will collapse, and no amount of local autonomy will make a difference in terms of how players will fare in the ensuing tumbling down of the structure.
We now have the same chat rep claiming to only work for Fenix, yet there they are dealing simultaneously with a live chat with a player from Adrenaline as they make this claim.
We had a similar thing going on with Rival. They too claimed they were completely independent, and there were some stark differences between the skins in terms of speed of payment and "roguery". However, it turned out the whole thing was a lie, the overwhelming majority were owned by the same 4 Canadian chaps, and all run through the same holding company. The "management" at each skin was nothing more than "super affiliates", and it turned out that when it came to deciding which players were not paid, bonus banned, etc, all had to obey the diktat of the "Rival player database" operated by the operating company.
It looks like we have a similar structure here, with the holding company being the one with the gambling license, and which ultimately calls the shots. Local management seem to have a degree of autonomy, but they still have a boss who calls the shots. For some reason, the team running Hello manage to do a better job than the team running Fenix, but this could easily change, much as it did with Rival skins, great one minute, and screwing over the players the next.
In this structure, the interdependence means that there is a high risk of the badly run skins bringing down the well run ones. If the holding company is deemed to be in breach of the licence held for them all, perhaps due to the actions of a bad skin, the whole lot will be brought down.
