Try changing your controller code like the following:

class ServicesController < ApplicationController
    def index
      @organs = Admin::Organ.all
      @services = Service.order(created_at: :desc).page(params[:page]).per(3)
    end
end

try this

Old code

@services = @services.order(created_at: :desc).paginate(page:params[:page], per_page: 3 )

New code

@services = Service.order(created_at: :desc).paginate(page:params[:page], per_page: 3 )
