TLDR at bottom. So, I got hired for a full time work from home tech support job. I did the interview, got my offer letter with a date for training to start, and filled out the onboarding paperwork. Then, the week before my start date, I hear absolutely nothing. This job is supposed to loan out equipment for work. I sent an email to the person who sent my offer letter. Basically just asking how/what time to report for training, when will the equipment arrive, just some loose ends that need tying up. No response. Then the weekday before training I get an email from someone about my i9 paperwork. "I see you have an appointment to complete the i9, please don't miss the appointment." No specific date or time given. I send an email back saying there must have been a miscommunication, I haven't heard anything about the i9 or anything really since I filled out my packet. Get a response: "I'm sorry, we will let you know when your i9 is ready. Please disregard the email." Then nothing. Day before the supposed start date I send an email to the person who messaged me about the i9 the day after training. Basically just explaining the past week's events and the fact that I have received essentially no useful communication. They say they are very sorry and will be escalating it to higher ups to see why the verification isn't being completed. They mention that there is a glitch in the system. The first day comes and goes and I can't get ahold of anyone. Now 4 days have gone by and I haven't heard a thing other than some automated emails about enrolling in their health insurance. I called the HR department today and they said they would send an email to the people who were supposed to oversee my training to contact me, but they don't have the power to do much else. I'm freaking out a little bit because I already resigned from my previous job pending the date I was given, and I don't want to start a new job just in case I get out of this weird new hire limbo i seem to be in. I need this job and can't really afford to not work for much longer. I'm worried about bills and mad about the lack of professionalism. I realize the current pandemic could affect things but no communication at all is too much. Does anyone have any advice or similar experiences?

TLDR got hired and filled out paperwork for a work from home job but because of a "glitch in the system" I haven't gotten the final paperwork and was unable to start on the day they gave me. Communication is also seriously lacking.
