Welcome to the forums. No, I am not new into the forums. I like making a new account in every FS game. Who knows? Maybe in FS24 I will be EUROFARMER24,lol.
Now, I understand your frustration. Pesonaly I don't like using the Helpers, and of course I don't want to use Courseplay, autodrive etc. I prefer to play the game in survival mode because I like to do everything by myself.
I understand you want a refund, but let me explain you. If you played 50 hours as you wrote, there is no way to get a refund. The only possibility to get a refund is if you will buy the game from Steam and you play it less than 2 hours.
Imagine, if we all play around 100-200 hours and then ask for refund. Do you know what would happend? Giants will go bankrupt.
Right now you have two options:
1. Stop playing the game.
2. Start playing it with a way you will enjoy it.
So, I would like to give you a suggestion, and of course is up to you to decide. Stop caring about AI helpers and try to play by yourself and try to enjoy the game. Believe me, in few months you will want to remove the keybinds of hiring helpers:).
As I said I understand your frustration, but I don't think it should stop you to keep playing. Avoid hiring AI helpers and try to discover the advantages of the game. Make some plans/goals, for example, focus into a production chain. Keep playing the game and in the next few months you will laugh when you will be thinking "darn, I asked for refund? Was I stupid?".
Is your choice and your decision. Either you keep playing the game or not, but refund is out of question.
Happy Farming.
