Update us if what had happened in the next couple of days because they seems to be doing thorough investigation and I don't know whats their reason for conducting that unless you are a suspicious player.
but taking that Long in investigating ? that is not fair , maybe it will take some time but not that longer .
hoping that you will still recover your funds since they are facing some issue recently .
If I understood correctly, they never told him that the investigation of his case will take 6 months, but they used that as a reference by saying that 20 days isn't that much but investigations sometimes can even take about 6 months or so, so he shouldn't be worried about that. He probably didn't understand the reference and thought that his case is going to take 6 months to get resolved or to reach a conclusion about whether he will be able to withdraw or not.
Fortunately, as we can see above, they have canceled his previous withdrawal and he has processed new withdrawals that got approved. So, they did what they said that they are going to get him an answer soon, and they have resolved his issue. Good for him.
