Split Aces Casino - 500 withdrawal not coming

After depositing and winning with no breaches of their very numerous betting terms and conditions I made a withdrawal.
After a long drawn out verification procedure I assume which was meant to frustrate my verification accepted, so fine and then withdrawal approved again great assumed everything OK then.
However that was 12 days ago after speaking online to their customer service agents have been told various time frames and was told it was actually paid 12 days ago, however today when I questioned how it is not in account and that no bank transfer no matter what would take this long, it was said it was only paid today and will be in my account in another 3-5 working days.
Of course there's no evidence it has been paid, and that I'm not going to spend my life every 3-5 business days online been misled by customer services about something which has never been paid.
