32Red Casino - Withdrawal of £30,000 still not paid after more than 2 weeks waiting

I withdrew £30,000.15 on the 03/07/18 I was informed this was paid on the 05/07/18 after sending verification documents. It's the 18/07/18 and I still have not received payment. I was told to wait 3-5 working days which was fine. The money was not in my account after the 5th working day so I contacted 32red and was told the money has been sent there's nothing they can do and that it may be that my bank is holding the funds and they need to be cleared. I contacted my bank and they inform me there is no sign of any money going into my account and to ask the company that's sent the money to do a forward trace to find out where the money has gone, so I ask 32red to do so and they tell me I need to wait another 5 working days for them to get the "tracking number". I have never had to wait anywhere near this long to receive a payment from an online casino. They keep reassuring me the money has been sent nut I still have nothing. After the 19/07/18 I will then have to get a forward trace on where my money is. This could take days or even weeks until I find out anything. I think this is unfair at the least they took my deposit money in seconds but being paid out seems to be a big problem.
