Actually, maybe it won't take up to 6 months, even if this is just an estimate, to be honest, for a long time investigating it won't look good in the eyes of all gamblers, it can take that long, I hope you don't violate the TOS or commit fraud so they have to investigate your withdrawal or they just want to make sure you're not money laundering.

If there are no problems I don't think the investigation will take too long either but if it's 6 months like that maybe there is some reason why they are taking so long to investigate, I think you need to contact them again to get confirmation about the results of the investigation and your withdrawal. because it's boring to wait for that withdrawal if we really need our money.
