DataStore not saving data correctly?

I've been trying to create a random name generator for all players whenever they firstly join the game, then save it through DataStore. However, each times I play the game I will just get a new name EVEN if the output says (4 times lol) the data has been saved. Help?

local DataStoreService = game:GetService("DataStoreService")
local dataStore = DataStoreService:GetDataStore("MyDataStore")

local function saveData(player)

    local tableToSave = {
        player.Character:WaitForChild("Values").Name.Value; 
        player.Character:WaitForChild("Values").Surname.Value
    }

    local success, err = pcall(function()
        dataStore:SetAsync(player.UserId, tableToSave)
    end)

    if success then 
        print("Data has been saved!")
    else 
        print("Data hasn't been saved!")
        warn(err)       
    end
end

game.Players.PlayerAdded:Connect(function(player)
    local data 
    local success, err = pcall(function()

        data = dataStore:GetAsync(player.UserId)

    end)

    local character = player.Character or player.CharacterAdded:Wait()
    local Name = player.Character:WaitForChild("Values").Name.Value
    local Surname = player.Character:WaitForChild("Values").Surname.Value
    local Names = {"Guren", "Yuuichiro"}
    local randomName = Names[math.random(1, #Names)]
    local Surnames = {"Ichinose", "Hyakuya"}
    local randomSurname = Surnames[math.random(1, #Surnames)]

    if success and Name ~= nil then
        Name = data[1]
        Surname = data[2]
        print(Name, Surname)

    else        
        Surname = tostring(randomSurname)
        Name = tostring(randomName)
        print(Name, Surname)
    end

end)

game.Players.PlayerRemoving:Connect(function(player) 
    local success, err  = pcall(function()
        saveData(player)
    end)

    if success then
        print("Data has been saved")
    else
        print("Data has not been saved!")
    end
end)

game:BindToClose(function()
    for _, player in pairs(game.Players:GetPlayers()) do
        local success, err  = pcall(function()
            saveData(player)
        end)

        if success then
            print("Data has been saved")
        else
            print("Data has not been saved!")
        end
    end
end)
