You were not lied to. You were told that ladder would not come at release and that they did not have a date for it.
You had 5 weeks to get a refund before release.
You chose not to.
You then played the game extensively knowing that invalidated any refund.
I don’t see a lie. I see a person who is angry that Ladder has not happened yet and is regretting not refunding during the 5 weeks they could.
If you are 37 then by now I am sure you are familiar with refund policies - and know that for software in particular if you use it you own it.
