1 week later adsl line still down

Problems with Adsl line. Logged call on Monday the 7th of Dec 2015. Followed up twice a day since then. Still no resolution. Escalated call. Due date today 14th Dec 2015 at 12:00. Call center agent said her supervisor will call me. That was 2 hours ago. Still waiting. What does one have to do to a Telkom Adsl line fixed. Looks like logging a call, escalating the call and calling all the time does not help.
