I've never really mentioned it elsewhere, but the last time I even considered doing something with oracle was I believe when they released the free-tier arm instance and I was just going to compile some of my projects to arm to see if they worked well.
Well since I'm not in the business of trusting a lot of corporations I decided to use a privacy.com virtual card that only had a one time transaction and would close afterwards. Well after signing up and starting the instance and doing some quick tests. I ended up coming back to it a bit later and found out the account was just out right terminated. After a while of going through support and looking around at what logs I could get, turns out they tried to do a $0.01 charge on the card and since it failed marked the card as stolen (or something similar.) And even with a long conversation with support they told me there was literally nothing that could be done, not even with proof of identification or anything. Even making a new account didn't work since something was matching and they were rejecting me making a new account (don't know if it was address, ip or my name.)
At this point I share the opinion that others here are sharing, no matter the reason never work with oracle. I'm just lucky they made the decision for me and I never even have to consider the choice again.
