Does anyone have any useful contacts for alerting this lounge to the presence of my laptop bag ?

I dashed off when my (late!) flight was called. I have the important stuff with me (eg laptop) but power cables, converter, phone charger...are in the lounge and I am in ZRH.

After waiting over 10 mins for Silver Exec club to answer, all I could get from the call centre was the general T4 lost property phone number. Which rings out unanswered .

All ideas greatly appreciated...
