It's natural that these CS people don't promise the time they need to work on your case because the team handling it hasn't given an ETA for this. This is a bit confusing actually, but it seems they haven't found anything definite about your gambling violation activities, or maybe your case is in the queue, we don't know about that.
Hopefully your case will be resolved quickly and there will be no prolonged problems and you can get your rights. However, on average, work like this sometimes takes a long time, please have a lot of patience.
