It is a problem players encounter if they are TOO honest with a casino. It is best not to elaborate on such a request, and also wait until the money actually gets paid and received before requesting anything like an account closure.
It seems many casinos consider a request to close an account as an implied admission that the player has a gambling problem, so no need to make it worse and TELL them you think you might be on that slippery slope if you have just had a nice win, and just want to have some way of blocking the urge to play it all back, which is the reason many players close accounts, or ask for short term exclusion.
I NEVER formally request an account to be closed just because I have decided to uninstall a casino and not go back for the forseeable future. I have loads of dormant accounts, and this at least leaves me free to return should they offer something that makes it worth the effort.
Many players have fallen foul of the industry's somewhat over cautious attitude to getting saddled with a problem gambler who wants their money back and will generate bad publicity pursuing it.
Had you just waited till they paid, and gave them the exact same request, they would NOT have been able to get the money back, and they would have just done what you wanted, which was to close your account. They will also have added your name to a problem gambler blacklist, which could lead to other casinos finding out about it, and possibly refusing registration, or even confiscating winnings upon the next withdrawal.
