Digitec (or any other Swiss dealer) 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, a suitable adapter if the mains cable is permanently connected.

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.
