Magento 1: Override A Method in a model class of a community module

I am creating a custom module to override a method buildCustomer() in file app/code/community/Ess/M2ePro/Model/Magento/Customer.php of Magento 1 Module Ess_M2ePro but seem not working. Can you check please. Here what I have so far.

app/etc/modules/myNamespace_M2eProFixPassword.xml

< ?xml version="1.0"?>

  
    
      true
      local
      
        
      
    
  




app/code/local/myNamespace/M2eProFixPassword/etc/config.xml

< ?xml version="1.0"?>

  
    
      1.0
    
  

  
    

      
        myNamespace_M2eProFixPassword_Model
              

      
        
          myNamespace_M2eProFixPassword_Model_Customer
        
      

    
  






app/code/local/myNamespace/M2eProFixPassword/Model/Customer.php

class myNamespace_M2eProFixPassword_Model_Magento_Customer extends Ess_M2ePro_Model_Magento_Customer
{
public function buildCustomer(){
     code here
}
}

This is the community Module config.xml of Ess_M2ePro

app/code/community/Ess/M2ePro/etc/config.xml

    
        
            
                Ess_M2ePro_Model
                M2ePro_resource
