How long it takes to add credits to account after receiving mail?
I have tried to add credits to my account in local office here: https://www.sozialbank.de/service/ihre-ansprechpartner/standorte/geschaeftsstelle-muenchen.html
They don't accept cash payments, so I had to send money by cash with email, what I have done on the 2nd of May 2018.
I've sent 13 euro by mail from Munchen on 02 of May 2018.
I have received notification from mailpost that mail was delivered to Berlin on the 4th of May,
How it will take to add credits to my account?
Thank you for the answer
