Fired ?? Please give me advice

I think I might get fired

So I got a new job at a restaurant that is opening up on July 5th . We can't work in the store or haven t been able to since it's not even fully done yet so I've been going like 20 minutes out of the way to work. We haven t really had a schedule it's just been whenever I see him I ask what time to come in the next day. He's been at the new store trying to get things together. On Friday night I text him asking when I should work he said 5 am go to the store youve been going to...he texted me Sunday saying I had it off. Then that night texted me saying to go in at 8 Monday morning I swore I thought he said to go to the same store I've been going to but I looked back at my messages and it doesn't say which store. Anyways I went but ended up leaving bc I was on the verge of puking literally everywhere so the manager at that store said I could leave (we listen to her when he's not around) I called the manager at this store where I live cause I had a missed call from him and he asked me where I've been at so I assumed he means on Monday and I told him what happen with me being sick and he's like well you was supposed to be here, I apologized said I had no idea. All he said was ok I have to talk to such and such (he trains the crew ppl) and that was it.

I see now maybe I should've confirmed which store he meant but at the same time I don't think its.fair bc they don't even know what's going on half the time we don't have a schedule and everybody just goes everywhere.wtf
