Anyone on here actually do the driver training?

I will try to make this short and simple. I've been driving for 19 years at the same company. They run little Hot Shots carrying their own product. They purchased a $5,500 so they could have a sleeper on the truck and save some company money but of course I have to have my CDL. I went to one of the schools that was listed in the South Carolina DOT system. Lucky me being 50 years old now I had a heart attack. So I had to take all the written test again and get another permit which was no big deal. The problem is that guy that was in their system as a school did not do anything on the computer. I found out later that was the ELDT. I called and called them but they no longer answer the phone and the DMV says that company is not in their listing anymore so I guess he went out of business is only thing I can think of. So the lady at the DMV said I need to go online and take that test which is really just a bunch of videos of common knowledge. I went to ELDT Nation and did that. I finished that then scheduled my skills test. The DMV calls me and tells me they have a red X beside my ELDT and I need to call the FMCSA to get it removed. Those people have not called me back yet. I need desperately to get back to work. I am not a sit around and do nothing kind of person and I am flat broke.. I went back to the DMV and the man that gives the test said I'm probably going to need a sign off and I don't know what he's talking about. How do I get this done? I have to do something. So I called the CDL help desk before the state and they said I would need a sign off. I don't know what they're talking about but how is the school going to sign off when he no longer answers the phone?. Not telling everybody my business but I'm not afraid to say my power got turned off two weeks ago. I need some help guys
