Promotion npc problem

[Zuxus]

When I buy a promotion I become for example master sorcerer, but when I relog I am sorcerer again. Help pls. Here is the script:

 local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local talkState = {}
local premium = { days = 7, cost = 20000, effect = CONST_ME_MAGIC_GREEN }
local promotion = { cost = 20000, effect = CONST_ME_MAGIC_GREEN }

function onCreatureAppear(cid)				npcHandler:onCreatureAppear(cid)			end
function onCreatureDisappear(cid)			npcHandler:onCreatureDisappear(cid)			end
function onCreatureSay(cid, type, msg)		npcHandler:onCreatureSay(cid, type, msg)	end
function onThink()							npcHandler:onThink()						end

function creatureSayCallback(cid, type, msg)
	if(not npcHandler:isFocused(cid)) then
		return false
	end

	local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid
	
	if msgcontains(msg, "Nop") or msgcontains(msg, "Nop") then
		selfSay("Do you want to buy "..premium.days.." days of premium account for "..premium.cost.." gold?", cid)
		talkState[talkUser] = 1
	elseif msgcontains(msg, "promotion") or msgcontains(msg, "advance") then
		if getPlayerStorageValue(cid, 30018) ~= TRUE then
			selfSay("I can promote you for "..promotion.cost.." gold. Should I do it?", cid)
			talkState[talkUser] = 2
		else
			selfSay("You are already promoted!", cid)
		end
	elseif msgcontains(msg, "yes") then
		if talkState[talkUser] == 1 then
			if doPlayerRemoveMoney(cid, premium.cost) == TRUE then
				selfSay(premium.days.." days has been added to your account.", cid)
				doSendMagicEffect(getCreaturePosition(cid), premium.effect)
				doPlayerAddPremiumDays(cid, 7)
				talkState[talkUser] = 0
			else
				selfSay("You do not have enough money.", cid)
				talkState[talkUser] = 0
			end
		elseif talkState[talkUser] == 2 then
			if doPlayerRemoveMoney(cid, promotion.cost) == TRUE then
				setPlayerStorageValue(cid, 30018, TRUE)
				selfSay("Enjoy your promotion!", cid)
				doPlayerSetVocation(cid, getPlayerVocation(cid) + 4)
				doSendMagicEffect(getCreaturePosition(cid), promotion.effect)
				talkState[talkUser] = 0
			else
				selfSay("You do not have enough money.", cid)
				talkState[talkUser] = 0
			end
		end
	end
	return TRUE
end

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())

try this script:

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

function onCreatureAppear(cid) npcHandler:onCreatureAppear(cid) end
function onCreatureDisappear(cid) npcHandler:onCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg) npcHandler:onCreatureSay(cid, type, msg) end
function onThink() npcHandler:onThink() end

local node1 = keywordHandler:addKeyword({'promot', 'promotion'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'I can see that you are ready to get promoted, I will take a fee of 20.000 gold coins aswell, are you absolutely sure?'})
	node1:addChildKeyword({'yes'}, StdModule.promotePlayer, {npcHandler = npcHandler, cost = 20000, level = 20, text = 'Auhmm... Auhmm... Auhmm... Ahh... You are now ready.'})
	node1:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Alright then. Come back when you are ready.', reset = true})

npcHandler:addModule(FocusModule:new())
