Not exactly the same problem but, my account renewal did not go through. When I contacted my bank, they said they responded yes to $1.00 probe SE sends. This means it was ok on my end. SE said an error occurred and cancelled my subscription. I do not have faith in the support ticked I filed.
The only thing different on that account since the last time it was renewed is the 15 days free time for preferred world creation level 30.
