Json – My Save/Load System doesn't work. The directory is never created

I have a static generic class which is used to load and save Data. I don’t have any compilation error, but the system doesn’t save or load. My project is on Unity.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO;

public static class DataManager
{
    public static void Save<T>(T data, string path, string name)
    {

        path = Application.persistentDataPath + "/SaveData" + path;

        if (!Directory.Exists(path))
        {
            Debug.Log("Create New Directory");
            Directory.CreateDirectory(path);
        }

        path = path + "/" + name + ".txt";

        Debug.Log("Save : "+path);
        string json = JsonUtility.ToJson(data, true);

        File.WriteAllText(path, json);
    }

    public static T Load<T>(string path, string name) where T : Savable, new()
    {
        path = Application.persistentDataPath + "/SaveData" + path + "/" + name + ".txt";

        Debug.Log("Load : "+path);
        T data = new T();

        if (Directory.Exists(path))
        {
            Debug.Log("Data Exist (Load)");
            string json = File.ReadAllText(path);

            data = JsonUtility.FromJson<T>(json);
        }
        else
        {
            Debug.Log("Data Don't Exist (Load)");
            data.Name = name;
        }

        return data;
    }
}

I put several Debug.Log() in the programme to find the problem, but I don’t find anything.
I als put a Debug.Log() just before the save and just after the save with the data it contain.

Debug.Log

As I saw in the Log, the first load is normal if we consider we don’t have any data. (The value after the name of the object are the value in the object.)

When the save happen the object possess the value after modification and the path is the same. It doesn’t find any directory so it create a new directory.

When I load a second time, it doesn’t find the data and use the default data again.

I need the data to be able to load properly.
