Digitec (or any other Swiss retailer) is obliged to supply electrical appliances with a Swiss plug. If the appliance is supplied with a foreign plug, a suitable replacement cable should be supplied if the mains cable is pluggable or alternatively if the mains cable is permanently connected, a suitable adapter should be supplied.
If the appliance is delivered without a suitable plug, complain to the customer service and insist on a cable or an adapter, free of charge.
