Sorry you had a difficult time with your Tesla.
I use EVGo almost all the time now with my Ford EV.
My EV is registered as "AutoCharge+" which means no app, no phone, no tower to interact with - just plug and charge.
You can even forget your wallet, phone or keys and even let others drive it to any EVGo fast charger to charge without any interaction.
EVGo will bill your credit card attached to it every time.
I also have the AAA/Auto Club discount attached which eliminates the $0.99 session fee.
EVGo rates are 3 different pricing tiers depending on demand and time of day.
Cheapest is late night thru early morning, then later till early afternoon goes mid tier and the highest tier is about the time everyone leaves work.
This is a recent charge at mid tier rate:
