Adobe double charges me and then cancels my yearly subscription while keeping the money?!

I have/had a yearly subscription, running for about four months, paid monthly. After being double charged in February (once via SEPA bank transfer, then via Paypal) I contacted the Adobe customer service. They veryfied my payment via Paypal and sent me an Email I was supposed to use as a receipt, so my bank can charge back the SEPA transfer. This is what I did.

Then, a couple of days later, on the 1st of march, I received an Email from Adobe: my subscription is cancelled (translated: "Confirmation of your cancellation"). I never cancelled my subscription. I also paid till the end of March at least. But now the subscription is gone and I can't even contact the customer service "because there is now current subscription"?

April fools coming early this year? What is going on and how can I fix this?

Any help is much appreciated.
