Phantom A1 usage after Free Trial ended – can't recreate Always Free VM

Hello, I have an Always Free account (eu-milan-1, home region) and I'm stuck with what looks like phantom A1 usage on my tenancy. What happened: - I had a single Always Free instance, VM.Standard.A1.Flex with 2 OCPU / 12 GB, within the Always Free limits. - On 6 November I requested a resize to 3 OCPU / 18 GB. It was rejected with LimitExceeded (my tenancy limit is 2 OCPU / 12 GB), so the instance stayed at 2 OCPU / 12 GB. - After that, the A1 usage counter showed 3 OCPU / 18 GB in use,
