Furious and Frustrated

I register my son for the second semester which we were told will start in July 2024. We paid for the registration in April already but til date haven't had any communication. Everytime we call to speak to the student councilors that assisted, we're told they're no longer with the company and get transferred to someone who will assist but the phone rings till it goes off the hook. Does this mean they left and now the company died? Can someone contact me like yesterday
