Verification issues and delay

I requested a withdrawal on the 8th of August. They asked me to send in verification docs which I did promptly. After not hearing back I spoke to someone on live chat and they said their finance team never recieved it. Around 10 emails later they magically got them when I emailed them to suppor­t@s­pli­tac­esc­asi­no.com. my withdrawal was then approved two days after I sent these. Skip to the 16th of August and I was then asked for IBAN and BIC details...again. I sent this the same day at 19:05. After chasing this up this morning two days later again the finance department had not recieved them but when I sent it again through support...5 times... They magically appeared. It's only for 100 quid but I find the whole process ridiculous and time consuming. Also Henry who I spoke to on chat was so rude and frustrating and I did end up getting angry at him as he was doing nothing to help me. On any other casino I have requested a withdrawal my documents and information has been verified and sorted within 3 days minimum. I think it is disgusting that they witholding funds from customers for so long. And looking at the reviews it seems to be a reoccurring theme. What is going to be done about this?? Why would I have to wait 2 weeks for their department to do their job?

I have attached screen shots of how many times I've sent in my documents to them. As you can see in the second picture I emailed 4 times within that thread. And was still told they had not recieved them.
