Hi there,
I'm on a slightly misleading 'free' Fiori course via openSAP.
Once I realised 'free' meant that I may be charged hundreds of dollars by AWS I canceled/closed my AWS account.
Unfortunately I can't seem to now delete my CAL instance because it's trying to verify my credentials with my non-existent AWS account 
Not quite sure how to get me out of this? Is there anyone that can help?
Thanks in advance,
Rob
