you need to be direct and objective:

have you been paid or not?

when you go to make a complaint, you need to tell all the details, you need to tell the whole story so that everyone is able to understand what you are going through, I will give you an example of what you should do:

start by counting the day you made the deposit, how much was the deposit amount (post txt id or print screen), then which game you played (if you played) and whether you won or lost, then count which one was the amount you tried to withdraw (post print screen of pending withdrawal if possible) and then tell us what support said to you when you contacted them (if possible post print screen of conversation with support), this is what everyone is wanting what you do, people are not speaking ill, everyone is right to ask you to do it
