Good need more no deposit bonus’s though

I have registered on 21st of July 2021. After depositing £1000 and winning over £8000 withdrawal for £8000 was requested. Instantly after hitting withdraw button I was sent email to verify my account by providing passport, driving licences, picture of bank card used for deposits and proof of address. On 23rd of July got email stating that verification was successful. After waiting further 3 days for withdrawal to be processed I contacted customer support via live chat just to get another email requesting my bank statement. Bank statement was sent but unfortunately not good as it didn’t show deposits made so I had to call my bank and request new statement up to date. After uploading new statement via website on Thursday 29th of July and waiting further 3 days for it to be verified I contacted customer support once again. As always people who supposed to help are clueless and cannot provide any information.
I’m sick of this and will be taking this further by getting Gambling Commission involved.
Practice used by this company is really doggy. I was told that this whole process is in place to protect my funds by making verification that payment method used for deposits and withdrawal belongs to me. However this only work one way as I cannot withdraw £8000 but they still allow me to make deposits of almost £9000 during verification process.
I would definitely not recommend them to anyone.
