WinTingo Casino - Verification & payment delay

Hi I had a win at winging of Tuesday just gone now it's Saturday which isn't a great length of time however to be sure I had zero problems on Tuesday I made a phone call to customer service as getting communication on live chat is useless.
Spoke to rep on phone was told to supply usual in my case photo I'd recent utility bill and credit card I explained at the time I have the most recent card I deposited with but a previous one I'm unsure of whereabouts I was told that's fine as long as I have the most recent one.
Now since then I have been in contact everyday as they have asked for something else everyday originally it was a more clear photo of my license as its faded a bit not such a problem then yesterday I look and my withdrawal had been reversed no contact from them so I call again and was told I was missing a document they asked for in which they hadn't. It was my older credit card searched the house hi and low found it sent pictures off. The rep I spoke to said it was all that was needed to finalise verification so I was happy. Few hours later I get an email saying I've not supplied them funny but about that was at bottom of that email was the stuff I had written on the email with pic attached. So fast forward to this evening I get an email saying they now need a selfie with my photo I'd which I found odd but sent it anyway then made another phone call spoke to rep told him it seems to be a delay in payment tactic as there's no where in their guidelines that states this is necessary. His reply is that it's required by the gambling commission. I told him that is false and have never had this sort of hassle with any other casino. He also said once I've sent the doc that they request that will be it and I'll be verified to which I replied that I'm having trouble believing this as I've been replying to requests all week and they just keep asking more did get a little cheeky and said I'm worried I'll get to Monday and they'll ask for a picture of my dog lol. He also suggested that I've never had this hassle with any other casino before because they don't take their security seriously. At the end after getting no where I said thank you for nothing it's time I came here to make a complaint so here I am. Nothing they have asked for is out of this world but really appears they are stalling perhaps it's because they think if they stall verification and get to the weekend I'll put my winnings back through the casino not going to happen if they don't get their act together it's not likely they will get another deposit out of me ever
