Non-existent response from "Project Management" during sales and installation process

I am experiencing very *********** customer service during my sales and installation process. I have app**** for a YaClick satellite connection at the end of Nov 2023. I received confirmation about my order swiftly after that, but that is when things started turning quiet. Even though I've paid my installation fee, I cannot get an update from anyone to tell me what is going on with my installation and when it will happen. I have spent hours on the phone waiting and when I am finally speaking to someone they put me through to Project Management and then I hang on indefinitely. I've had numerous call center people telling me that they will find out and get back to me. It has been weeks now with no one phoning me back. I have tried numerous channels - email, whatsapp, call center, but nothing. No one can tell me what is going on with my order.

I've even called the local Vox office in Nelspruit and the person there confirmed that it's "in progress" and they will request from "Project Management" that someone give me an update call. No call yet after two days.
