No Internet and no one to help fix it

I've been without Internet for more than a week, and with degraded service for almost two weeks. I've logged numerous requests for service and the tickets are simply resolved and the service not restored. I'm supposed to have uncapped ADSL but I'm paying for useless service. Finally on Tuesday I received an sms from Telkom advising that they've detected an outage in my area. Can someone please help resolve this as I'm working from home due to Covid19
