That customer support chat is from someone else from April 25th.

It is not from the blog poster. There is no indication that the blog poster communicated with Oracle Support in that blog post. Everything from Oracle support in the blog post is from other people and paraphrased Q&A on the Oracle Community Support forum (where the support became a private correspondence with the person rather than out in the open).

At the very end:

> Q: Did you create a thread in Oracle Community forum?

> A: Yes, no answers.

And digging into the FAQ for the free tier...

> Does Oracle Cloud Free Tier include service level agreements (SLAs) and technical support?

> Oracle Cloud Free Tier does not include SLAs. Community support through our forums is available to all customers. Customers using only Always Free resources are not eligible for Oracle Support. Limited support is available for Oracle Cloud Free Tier with Free Trial credits. After you use all of your credits or after your trial period ends (whichever comes first), you must upgrade to a paid account to access Oracle Support. If you choose not to upgrade and continue to use Always Free Services, you will not be eligible to raise a service request in My Oracle Support.
