MS 62 prob-free turns into Rim-Filed, cleaned MS 60

NOTE: Everything in this journal is my opinion. I make no claim as to factual content.Did anyone experience difficulty with a "guarantee?"NOTE: I do not claim that there is any truth to any statements made in this journal entry. Statements are from my personal interpretation.It took 2 resubmissions to get the correct grade. They have been ignoring my email and phone requests for their guarantee for several weeks. The first grade review resulted in my problem-free 1921 Peace Dollar remaining at MS 62. The second time (I knew they were wrong), it came back as Rim-filled, Cleaned MS60. I spent a fortune in shipping and insuring, plus the original purchase. For several weeks, I have been leaving phone messages and sending emails for my refund / guarantee & nobody responded. PS: For my second submission, I requested that they look at the file mark on the rim.....Photographic "proof" available upon request.
