The documents for the new Cumulus credit card state that invoices can only be obtained free of shipping costs via the one app. In the app there is a link to the eBill website and that this option must be activated via e-banking or eBill. So far so good. Now it would be helpful to know who the biller is. Migros Bank, Cumulus credit card or Visa are not listed in the eBill directory. I would be grateful for a tip.
