This is an awful excuse. Every single Minecraft launcher gives you the ability to select what version of the game you want to use. You could have very easily switched to a different version. You clearly had the brain capacity and knowledge to install and use our own client in the past, so "I don't know how to download it" is just a flat-out lie.
You also literally said you don't care when you were called out for cheating and this is nowhere near your first time banned for cheating.
