New Showmax app is *******

We have a 2015 Hisense smart TV. Previously we watched Netflix on it and it was preinstalled on the device. I subscribed the to the full package last week and was unable to connect to the new Showmax app. The technician at Showmax informed me via the instant messaging bot that the new Showmax app only supports devices newer than 2020. Nowhere on the website is there a warning that the older smart TVs that worked previously will not be able to stream Showmax anymore. I sent an email and asked for my money back and was told someone would contact me. Needless to say, no one has. Poor service from Showmax and even worse service by updating your app and thereby eliminating many people that had suitable devices before the upgrade.
