REL subwoofer 60 day Price Protection


I purchased a REL Acoustics subwoofer in June 2020.  They claim to have 60-day price protection.  In July 2020 they offered the same subwoofer at 100 dollars less.  I asked them to honor the price protection and credit the difference.  They did not even respond to my email requests.  Has anyone had a similar problem?  Anyone have a suggestion.  It is a very nice T/7i speaker.
