Unfortunately you won't like the answer. The mob will forgive you if you don't have a bot for them once but if you try this twice in a row it's 'game over'. There is no way to avoid the mob, they don't tolerate deadbeats!
Read the Journal Notes and do EXACTLY what it says to do when they ask for a sex bot. No exceptions! After you give them this bot keep playing a while and things will develop. You'll have to use the grey market to get parts or get really, really lucky at the dump. There's also the online store but it's expensive. Also, you'll either need to get lucky scavenging a bot at the dump that has strong social skill or go to 'Night School'. It's best if you don't pay off the debt in 'Framed!' until you've built up some skills and have money left over. Good luck!
Another player wants me to change it so you can train a bunch of combat bots and start a war with the mob!
I had to disappoint him, that's not the type of game I want to make. Cheers!
