Vox Kimberley gives bad service

Since I have joined Vox it has been a worst experience. I took out a LTE package last year October and January I moved to the Satellite 10mbps uncapped package. The LTE was supposed to be moved to the Satellite package as per conversation with my salesmanager. He decided to cancel it and not inform me. I have been calling him and all he says is he will be getting back to me but never does. He no longer picks up my calls and has become rude. He sent me a whatsapp that they made a mistake with my account. I have all the mail conversations with him and the accounts department. I have been sending mails nobody at vox has ever gotten back to me. My account has been canceled and even sent mails for legal payments. The fault was not on my side. I have been asking for help from vox but nobody gets back to me at all. Can I honestly get help
