Ehy does my withdrawal keep getting cancelled?

My withdrawal keeps getting canceled for unknown reasons, and I am devastated. It has been three weeks of trying, but I am nowhere near giving up. Just pissed. They keep giving me poor excuses for why my withdrawal isn't approved. First, they told me that I couldn't withdraw during the weekend because it wasn't the time for withdrawal. Okay, fair enough. People are allowed to take a day off. So I try again on the weekday. But they still couldn't approve it. This time they didn't even bother to give me any reasons. The next time I try there is the 'temporary maintenance' issue. The list just keeps going on. I just want my money, this is ridiculous.
