Talk to the people who run the network
No call-centre script, no tier-one triage. Technical enquiries reach engineers who can read a SIP trace, and commercial ones reach someone who can actually quote you.

Live service affecting?
Call +27 21 017 4119 rather than emailing. If you do email, put the affected prefix or number in the subject line — it routes straight to an engineer instead of a queue.

Engineers, not a ticket queue
Zephyr is run by the people who built it. When you escalate, you reach someone who can change the routing, not someone who can only log that you asked.
