Whoa!? I've lost my pass and license!?

On the Yesterday morning, While I was being getting ready to leave the workplace after a night work, I'd I noticed that my phone's LED flashed was flashing. Someone who I don't know had calledand left a voice message. It He/She said,"I'm Yokohama station's officer. We keep have your commuter pass and insurance card right now. Please come and take them until before Aug. 8. Bye".

I was confused and searched my bag. The card case was there; however the pass, the insurance card, and my driver's license kept with them were all lost.
I went to the station thinking "If I've lost the license, what should I do?"

Fortunately all of them were kept there. I was relieved and went home back back home.

Good work. Looks like your many issue is related to the tense of a word which changes if something has happened in the future, the past or the present. It's one of those things where plenty of practice will help.
