HR Rep set up an onsite interview with the hiring manager at the end of our zoom meeting. I filled out the form she sent over that had to be completed for my interview and when I showed up, I was told that the hiring manager was not aware of the interview, nothing was on his calendar. This was a Friday and I immediately sent an email to HR to confirm if I got everything correct, and no answer. I sent another email Monday afternoon explaining again how I showed up, and asked if I got the information wrong - still nothing. I find it rude that she won’t even respond to say I’m sorry for the miscommunication, and usually would leave it alone, but this job is perfect and I can expand my career with them.
The hiring manager knows I’m a candidate and is aware I showed up for an interview that was scheduled, should I try to reach out to them?
I can easily figure out the email address off of HRs format, or I was thinking of sending a message via LinkedIn just to relay that I am interested and have been trying to reschedule.

HR recruiter never notified the VP of the on site interview she scheduled with me. I showed up to the location and was met by someone who said the VP is traveling, he texted him for me and the VP said he was aware of who I am and that I am a candidate but was not notified or an interview. The guy helping me even told me that the rep isn’t the smartest of the bunch. I immediately emailed the HR rep to confirm if I got the date/location wrong and that was a on a Friday, come Monday still not response. I reached back out to say I’m still interested and nothing. Is it reasonable to email the VP to let them know that I tried to contact the rep and that I am still interested?

I understand that it could be HRs mistake or even the VPs by overlooking. I’m just curious where I should go from here. as of right now, I think I did my part by reaching out to confirm if i got the right time and date correct. I think the least she could do is at least acknowledge that she received my email and apologize and get back to me, but it’s bugging me that she hasn’t done that.
