Hopper complaint: False advertisement with price freeze

I did a price freeze with Hopper for a flight on June 20, for a total of $180. The flights were originally $298 and the $180 was supposed to be added to the final balance, but when I went to check out, the $180 was not added. I reached out to the company on June 26, a day before my price freeze was up, and was advised the page I saw during check out was wrong and a glitch that they were working on. Initially, I only asked for them to apply the $180 at check out as their page said, and they continued to share that this was not supposed to happen. Instead of honoring their word on their app, they continued to let me know my deposit was non-refundable per their terms and conditions. They continued to tell me that I was not supposed to have my DEPOSIT of $180 applied and that it was used to hold the tickets. I searched the terms and conditions as well as other parts of the app and it is shown in two places that any deposit for a price freeze will be added to the final balance at checkout. Hopper lied and said this was not true. When I sent a copy of the page and highlighted this, Hopper refused to acknowledge this, and stopped all communication with me. I am now requesting my $180 to be fully refunded to me and I feel that something needs to be done about this company stealing money. If I must, I will seek legal council although, I feel that is extreme, I do not want to lose money with the way the economy is today. I have attached proof of all that I have shared here. The price freeze in the terms below shows at number 6 that this should have been done. I can provide more proof if needed.
