I am still struggling on how to do a time ban. Any help?

I honestly dk what I am doing wrong. It works to ban someone but when they join back it doesnt kick them again.

local dds = game:GetService('DataStoreService')
local bandata = dds:GetDataStore('bandata')

game.Players.PlayerAdded:Connect(function(plr)
	if plr.UserId == bandata then
		local success, banTime = pcall(function()
			return bandata:GetAsync(plr.UserId)
		end)
		if success then
			if banTime >= os.time() then
				print('Yees')
			else
				plr:Kick('\n you are banned.')
				print('you are banned.')
				print('Time Left - ', (banTime - os.time))
			end
		end
	end
end)

game.Players.PlayerAdded:Connect(function(plr)
	if plr.Name == 'CRAZYQUACKY84' then
		plr.Chatted:Connect(function(ban)
			local args = ban:split(' ')
			if args[1] == ':ban' then
				local plrBan = game.Players:FindFirstChild(args[2])
				if plrBan then
					bandata:SetAsync(plrBan.UserId, os.time()+180)
					plrBan:Kick('\n you have been banned')
				end
			end
		end)
	end
end)
