What else should I do?

I started work at a brand new location for a restaurant that has a few other locations in the DFW area, they did a pop up shop for the World Cup that I worked shifts on for a month and then they closed the restaurant for two weeks for renovations. My boss told me I’d be out back to work full time in August when they opened again,on 8/1 I said “Hey! I just wanted to check in and see if you knew when I might be coming in next now that (restaurant name) is reopening soon. I also wanted to ask if there was any additional training I need to complete before my next shift? Thanks.” So he answered a day later and said “There will be a week of training starting most likely the week of (8/10) as I have an open expo position if interested. If you’re wanting to serve, i’d have to get you in for a sit down with (co worker name).” So I didn’t think that warranted a reply but on the week he said there would be training I texted on 8/11 “Hey, I just wanted to follow up since you mentioned training would most likely start this week. I’m still interested and wanted to see if there’s a day/time you’d want me to come in!” So he did not respond for 6 days so I texted again yesterday and said “ Hey, I’m following up on my message from Tuesday, I haven’t heard back and wanted to confirm if I’m still going to be on the schedule or what’s happening with that. Please let me know when you have the chance” and I still have not received a response, I don’t know what else to do and I don’t know why he wouldn’t just tell me I’ve been terminated?? Do I try calling the new store, their number isn’t online yet since the location is brand new and they just had their first opening day on Friday 8/14. What else can I even do??
