Openserve Contact Details

Openserve does not publish a customer contact number or call centre. Its Contact Us page lists the email address info@openserve.co.za, an online enquiry form, and its office at 61 Oak Avenue, Highveld Techno Park, Centurion, 0169, and says all responses are given through digital channels, with no call-backs. To report a fibre fault, Openserve says to contact your internet service provider (ISP), not Openserve. The Telkom Group fraud hotline, listed on Openserve’s website, is 0800 124 000. Every detail below was read from openserve.co.za on 14 September 2026.

Is there an Openserve call centre number?

No. Openserve’s Contact Us page gives an email address, an office address in Centurion and an enquiry form, but no telephone number, and it states that “all responses are given via digital channels (no call-backs)”. Openserve’s FAQ explains why: as a wholesale infrastructure provider to ISPs, Openserve does not have a view of you as a customer on its system and relies on the information your ISP provides. Searches for an “Openserve contact number in Pretoria” usually lead to the Centurion office above, the only Openserve address on its contact page; for help with your own connection, go through your ISP.

Openserve fault reporting

Openserve’s FAQ says you cannot log a fault with Openserve directly. Your internet service is with your ISP, and only your ISP can see you as a customer. Contact your ISP, which will give you a query reference number and help you troubleshoot. If the ISP finds the problem is with the fibre infrastructure, it contacts Openserve on your behalf, and Openserve sends accredited technicians to assess and repair the fault. The Contact Us form also warns: “Openserve is not an internet service provider (ISP). To report a fault, please contact your ISP directly,” and links to an ISP directory.

Before you contact your ISP

1. Check that the electricity is on and that your router, WiFi equipment and the Openserve fibre box (ONT) are plugged in and switched on.
2. Look at the lights on the ONT. Openserve’s ONT support guide says a solid green Power light means the device has power, solid green Broadband (PON) means your service is active and authenticated, and the Alarm (LOS) light should be off; a solid red Alarm light means loss of signal.
3. Check all cables are secure; Openserve says turning the device off and on again may also fix the problem.
4. Check for outages or run a line test on the Openserve Connect App, which can also generate a ticket.
5. Contact your ISP with your service number (B-number).

Your B-number is a 10-digit service reference linked to your Openserve connection at a specific address. Openserve says you can find it on your monthly bill from your ISP, and that it helps identify your line for upgrades and repairs.

Openserve email address and enquiry form

For non-fault enquiries, email info@openserve.co.za or use the two-step form on openserve.co.za/contact. The form’s enquiry options are order and application queries, report an issue, prepaid bundle enquiry, complaints, follow up on faults and issues, “Do I have Openserve Fibre in my area?”, accounts and billing, and other. Openserve asks you to be as specific and accurate as possible. The website also has a Navigation Bot and a virtual assistant to direct you to the right information.

Switching ISP and fibre installation

To change ISP on Openserve fibre, tell your current ISP first. It arranges the switch with Openserve on a date that respects your contract’s notice period; Openserve says the earliest switch date is 24 hours after the ISP places the request, and it only releases your service to the new ISP on that date. Give the switch date to your new ISP as your start date. Openserve’s FAQ also says residents and homeowners’ associations do not pay for Openserve to install fibre infrastructure outside premises, but an ISP may charge an installation fee for the final connection after you order. Openserve also notes that from 1 June 2026 only 30-day prepaid recharge vouchers are available.

Reporting fraud, cable theft and vandalism

Openserve’s “Speak up” page directs reports of fraud, corruption, theft, vandalism and sabotage, including cable or solar panel theft and damage to infrastructure, to the Telkom Group hotline run by Advance Call. It is open 24/7, you can stay anonymous, and you get a reference number: call 0800 124 000, WhatsApp 081 222 5999, SMS 48691, email telkomhotline@behonest.co.za, visit behonest.co.za, or post to BNT165, Brooklyn Square, 0075.
