I imagine this is not going to be considered good news, but what you all have been reporting quite fits the situation when the casino is overwhelmed by requests.
In such situations, though, there is no other certainty than the time. The casino must simply muster its human resources and catch up with the delay. So, logically, if this is the case, they have little time to spare on emails through which players, for example, keep asking the same questions over and over again, and I can also imagine new withdrawals won't be accepted until the delay has been dealt with.
As I said, it is unsettling, but the solution is sadly quite obvious. 🙁 Patience.
