So I been using the service for a couple months now, and I been accumulating charges on my free account related to "Block Volume - Performance Units", which is small 0.03+ charges added to default "Balanced Setting" free disk volume each month, and 0.03 a day is smallest amount it accumulates, when hosting stuff on there I accumulated 0.55 cents. So if you want truly free, you need to select "Lower Cost" by placing the slider down to 0 VPU. Still I feel like it's a matter time with all these hidden not so free nobs until I get slammed with big cloud bills. Side note, can't delete my Tenancy (get an error) or my Account(waiting for something from support). Edit* $0.55 for this month, supposedly I owe $10.56 this year for these VPU's, but I am free tier so not sure how this is going work?
