Helping great customers like you is why I'm in this business. Thank you so much for your business and great feedback.
Took a little longer then I expected. I was part of that problem also but I had to send paperwork twice because of the timeframe that had nothing to do with me . Overall I was pretty satisfied considering the distance we're apart. Good job....

I am glad to receive your response. How can I better improve myself to a 5-star rating experience?
William was great but it did feel as soon as someone else was involved we weren't important and would be asked to send stuff we already had. Just seems like we weren't a priority.
