You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: payment_method.rb
    path of file: ./repos/pay/lib/pay/stripe
    
    the code of the file until where you have to start completion: module Pay
  module Stripe
    class PaymentMethod
      attr_reader :pay_payment_method

      delegate :customer, :processor_id, to: :pay_payment_method

      def initialize
    
      def self.sync(id, object: nil, stripe_account: nil, try: 0, retries: 1)
        object ||= ::Stripe::PaymentMethod.retrieve(id, {stripe_account: stripe_account}.compact)
        if object.customer.blank?
          Rails.logger.debug "Stripe PaymentMethod #{object.id} does not have a customer"
          return
        end

        pay_customer = Pay::Customer.find_by(processor: :stripe, processor_id: object.customer)
        if pay_customer.blank?
          Rails.logger.debug "Pay::Customer #{object.customer} is not in the database while syncing Stripe PaymentMethod #{object.id}"
          return
        end
