Reading binary files and fill vector c++ [duplicate]

I am studying reading/writing to binary files with C ++, i'm trying to apply with object lists,

    class Customer {
     public:
      int code;
      string name;
      void ini(int code, string name);
    }


    list<Customer> *customers;
    customers = new list<Customer>[2]; 

    Customer *cl = new Customer();
    cl->ini(17, "John");
    customers[0].push_back(*cl);

Writing method:

ofstream wf("customers.dat", ios::out | ios::binary);
for(int i = 0; i < 2; i++) {
    wf.write((char *) &customers[i], sizeof(Customer));
    cout << i << endl;
}
wf.close();

And reading method:

list<Customer> *customer2;
customer2= new list<Customer>[2]; 
for(int i = 0; i < 2; i++) {
    rf.read((char *) &customer2[i], sizeof(Customer)); //some way of using the push_back by here?
}
rf.close();

after debugging, the recording seems to go well, however when I do the reading, only the first item of the first vector is loaded, the loop cannot find an end and the program stops.

for(int i=0; i < 2; i++) {
    cout << i << " ";
    for (auto x : customers[i])// here fails
        cout << x->name << endl; //print the first member and break
}

what is the correct way to manipulate object vector lists?

P.S: For the sizeof, i've already tried: (customers, Customer, customer[i], customer2[i])

The entire code
