You misread the terms and conditions of Zwift trial. You do not need to Google around for this information, you should go to Zwift web site. Once you subscribed to Zwift trial (i.e., created your user name and password) and your avatar started moving for the first time, you have 7 days of full unlimited functionality. After 7 days, unless you subscribed, Zwift switches to a free mode in which you only can ride 25 km per month. Your user account and all your rides and badges are preserved in Zwift even if you cancel your subscription.
If you avatar does not move, it most likely means you did not get your power meter connected and Zwift does not know that you are moving. Do you have a bike trainer? Does it have a power meter? Sorry, it is not listed in your description of the gear which you got. If you a runner, you also need some gear - either a Footpod, or a treadmill, or better yet, both. But for runners, Zwift is free.
If you do not have a power meter but can only measure speed, you need to configure zPower in Zwift to calculate it.
If you post a snapshot of your Zwift connections screen, this community would be able to help you even more.
But since you are giving up, it looks like you are not looking for advice. Sorry to hear it did not work out for you.
