They promised to try to respond within 20 days.
In any case, I would warn anyone to make a deposit in this casino for now. There are so many similar complaints that there are only two options. Scam or failure.
...
Has it been 20 days since you first posted your complaint here? If not, then it's better to wait until the time promised by customer service. Don't be too hasty,
Not hasty too especially also with discrediting the casino to other people like he has said.
If a casino promises you a response within a certain period, you should understand that there are other issues that they are attending to as well that have come before your own and they have to put you in a time frame to ensure that they are able to satisfy everyone.
I am with @kofemaniac on this and I don't know why some of you talk carelessly as if you don't have any human feelings, but things change when you are in the shoes of the complainer. At times, it's better be silent in some discussion so that you don't look either clueless or biased due to one reason or another, especially if the casino is paying you. For fairness' sake, is 20 days not too much for any serious casino to respond to queries? What wait are you preaching again when he already pointed to the 20th day himself? "To whom more is given, more is required." If it is more capable hands due to a large customer-base, let them get it, it's unacceptable for the customers of a serious establishment to wait more than 7 days to get a response, not to mentioned the 20 days.
