Vodacom Fibre provides no back up service

My boyfriend's mother has been without fibre for 2 weeks. We have phoned the call centre on *** four times already. Nothing gets done about the problem. Call centre agents refuse to get a manager on the line who can sort out their incompetence. On 26 Aug she phoned in and received a service number from Ndileka: SR ***. On 29 Aug I phoned in: spoke to Nomhla who promised to escalate the matter. She informed me that the ticket had been closed. ( without it being resolved ) On 31 Aug I phoned : Asemahle said the line is active. On 2 Sept my boyfriend's mother phoned again . Bonje promised to get back to her the same day. I phoned again today and spoke to Mpumzi who refused to give me the supervisor's e-mail address.
