Dear Mr. Nakata.
I am following up as said in my last message.
Having not heard from you causes me concern that Customer Satisfaction is not high on your list.
I forwarded my last message to Yamaha Customer Support USA on July 27 hoping to hear back soon as well. As of this correspondence, I have not.
Please take my contacting you as an indication of dissatisfaction with the repair process and product quality. My frustration grows.
Having been employed in customer reaching positions, Customer Satisfaction was at the top of my priority list. I'm hoping I hear from you in the next few days. I will continue to follow up with emails using this correspondence method until I hear word from you or Yamaha Customer Support.
Thank you for your attention in this matter and your consideration for my request to upgrade given I have been without my receiver for almost 2 months now.
