Topic: Shift to the Starter Plan impossible?

I have problems shifting from the free tier to the starter tier 25 Gb (yearly payment). A week ago (as my 3 Gb free cloud was full), I followed the instructions to Upgrade to the 25 Gb plan (private customer, yearly). I payed with PayPal on 18. July and the payment came through to "Xcerion Aktiebolag
support(at)xcerion.com +46 004613214400". However, a week has passed and I am still on the free tier and cannot use my cloud. What happened to my payment? It is impossible to reach anyone on any address to clear the situation, please help!

Best regards, Anna
