Helppp

So I like received a contingent job offer and I went in person but they didn't ask me to fill out any paperwork and they said there would be a background check. It's been like a week and I haven't heard anything and they were supposed to contact me on Tuesday if they went through with it or not and they haven't. I can't get ahold of anyone and I've tried to look at the status on the candidate home screening but It won't pop up cause I initially applied for a different position and It was like we don't have this but we have thissss.

Like what do I do??? ​​
