I just read your reply properly and through out. Bitsler is proper big online crypto casino. With loads of customers and I even think it is legal and regulated OR AM I WRONG? All proper regulated and legit business should do the best for their customers. Because shit happens... Also the thing is that they can get the coins whenever they actually need them and they arent like they got no money. They could just cover it as its still in their wallet which is in their posession. I got a bit confused when you said ''You gotta be nice to them and soft'' Im nice and soft to my daughter because shes only 6. But this is a big gambling business , no one should ever have to beg and should get best support possible from sites like bitsler and others.
The fact (or the problem) here is that, it's nobody's fault, but your mistake which caused you to land in this situation, else why would you be talking about bitsler's support?
Be it your daughter or any professional business, you must be knowing that if you want to get your work done (like asking your daughter to sit calm or asking this big business), you need to cherish them with some love and care. Seriously, nobody is asking you to get into their shoes, just stay calm because it's your money and you committed a mistake. And I hope you won't repeat this in future taking this as a lesson.
