Vodacom voicemail issues

[LandyMan]

When trying to setup my voicemail (was active for 21 years and deactivated earlier this year) I am getting stupid errors on my Galaxy S8+.
When trying to setup via USSD, I get "Connection error or invalid MMI Code".
When trying to set up directly on the phone I get the attached.
Any ideas from anyone?
