The fastest route to a resolved internet fault is rarely the call centre. Most South African providers now resolve faults through an app, a WhatsApp line or a support portal, and those channels leave you a written record that a phone call does not.
This page sets out the verified operator routes and what to have ready, so the call you do make is one call rather than three.
Before you call: four checks that solve most faults
- Check for a known area outage. Every operator publishes them. If yours is listed, calling adds nothing.
- Restart the router, and wait the full two minutes. A partial restart is the commonest reason a fault reappears an hour later.
- Check whether the fault is on one device or all of them. One device is a device problem; all of them is a line or service problem, and saying which halves the call.
- Check the account is paid. A soft-locked line looks exactly like a fault, and a surprising share of reported faults are suspensions.

Short codes only work from that operator’s own network. Dialling 135 from another network reaches nothing, which is why people conclude a line is dead when it is not. The alternative numbers above are the ones to use from a different network or a landline.
What to have ready
- Your account number and the service address. A line is traced on the address as much as on the account.
- The exact time the fault started, and whether anything changed just before it: weather, a power cut, building work, a new device.
- The lights on the router, described as they actually are. Support diagnoses remotely from those lights.
- A speed test result, if the line is up but slow, with the time you ran it.
- A pen for the reference number. Ask for one every time. Without it a follow-up starts from nothing.
If the fault stays open
- Ask for the network operator’s reference, not only your ISP’s. If it has genuinely been escalated, that reference exists.
- Put it in writing once a call has failed. A written query creates a dated record and starts a clock.
- Quote the provider’s own published turnaround time. A fault open beyond it is the strongest complaint available, because the provider set the standard.
- Ask about a pro-rata credit for the days without service. Providers rarely offer one unaided.
- Do not cancel a debit order to force attention. It creates arrears, a suspension and a credit listing, and it does not fix the line.
Complaints and escalation
Unresolved complaints about a licensed operator go to ICASA, which will ask for the reference numbers and proof that the operator was given a chance to answer.

Why the same fault gets three different answers
Anyone who has phoned an internet provider three times about one fault knows the pattern: three agents, three explanations. It is usually not incompetence. It is that a connection has several layers and the agent can only see some of them.
- The first-line agent sees your account and the line’s status, not the network. If the system shows the line as up, that is what they will tell you, and it can be true while the service is unusable.
- Speed and latency are different problems. A line can deliver its full speed and still be useless for calls or gaming if latency is high. Say which one you are experiencing.
- Wi-Fi is not the line. A large share of reported faults are Wi-Fi coverage inside the house, which the provider cannot fix remotely and which a cabled test will identify in a minute.
- Congestion looks like a fault at 20:00 and vanishes at 06:00. If the problem has a daily pattern, say so, because that points at contention rather than a break.
- Ask for the fault to be escalated to second line once first line has exhausted its script. That is a specific request and it changes who looks at the ticket.
Run one test before every call and quote it: a speed test on a device connected by cable, with the time you ran it. It removes Wi-Fi from the argument and gives the agent something to work from instead of a description.

Frequently asked questions
Why does 135 not work from my phone?
Short codes work only on the network that owns them. From another network or a landline, use the operator’s alternative number: 083 135 for MTN, 084 135 for Cell C, 082 135 for Vodacom.
My ISP says the fault is with the network operator. What now?
Ask for the network operator’s own reference number. If the escalation is real, that reference exists, and your ISP can quote it. If it does not exist, the fault has not been escalated.
How long should a fibre fault take?
It depends on the network operator and the cause. What matters is the turnaround your provider publishes. Quote that when the time passes rather than arguing about what is reasonable.
Can I get money back for the days I had no internet?
Ask for a pro-rata credit, quoting the fault reference and the outage dates. Providers seldom apply one unprompted.
