No feedback from Vodacom no resolution

I've logged an incident on Friday, 9 Sept, no calls, I had to follow up, and still as at today, I need to follow up, no resolution up to date and tomorrow is Friday AGAIN! No one gets back to, despite escalations, you cannot get a direct contact number of a manager, the emails do not have signatures on....pathetic to say the least - no way to get into contact with anyone without explaining your situation Ober and over. Incurring additional costs because the service that is supposed to be rendered is not working.....
