Problem is, mostly they say something like 5 days and then they come with some lackluster excuse to either keep your account suspended or it will take longer. I mean the guy made 2 simple bets, not even big amounts or huge bets, yet they start an "investigation" right out the gate. That's classic betby and honestly annoying to see.
Sure I understand why it would seem so to you, since most of this platforms are just used to dragging things out with excuses. But in this particular case, they have already provide the cause and timeframe, so I think it is too soon to conclude that this is one of such situations.
In addition, saying that the bets were simple does not imply much on their part. Because majority of these checks are done according to some patterns that we are not able to see and not just how big or small the bets look.
I believe the key is to understand whether they will indeed stick to the 5 days they said. And if the platform start to delay after that or go quiet without still providing solutions, then your argument would be more reasonable. At this point, it is too early to call it so.
