Hughes review: no equipment no refund

Account number SME00119931 Huges Net I had an installation scheduled for 1/28/19 and it could not be done because my phone system is to old. I have waited for my refund and today was told I will be paying for the installation. I am not paying and I am willing to take the matter to court. I am working in a burn area already Camp Fire victim and have now been ripped off by you.
The installer was at my business for about 15 minutes then told me it was not possible to provide phone service because the phone system was to old. That is why I went with your company. This is a business. I have a hot spot but no phone service because of the fire. He took his equipment and left. All I want is my $239.92 back. You have the money and your equipment and have had them both since the 28th of January.
What I need from you if not my money is an address for your corporate office so I can send court papers and a judge can decide this appropriately.
Thank you for your time.
