EOH was a large South African technology services group, with its head office at Waterfall in Midrand.
EOH rebranded as iOCO, which is why the enquiry address it publishes uses the ioco.tech domain. That is the correct address rather than a mismatch.
Correspondence addressed to the old name still reaches the same organisation. Where a supplier or an employment record refers to EOH, the current entity is the one to contact.
This page covers how to contact iOCO, formerly EOH in South Africa. The details below were taken from the official iOCO, formerly EOH contact page rather than from any third-party directory.
ContactDetails.co.za is an independent directory. We are not iOCO, formerly EOH and cannot act on your behalf. Everything on this page is a routing aid so you reach the right official channel quickly.

Self-service options before you call
- Check the official site at ioco.tech, which carries the current contact details and any online enquiry form.
- Email to [email protected], which gives you a written record of what you asked and when.
- Calling outside peak times. Monday mornings and the hour after 17:00 are usually the worst for South African contact centres.
What to have ready before you call
- A clear one line summary of what you need resolved.
- Your account, order or reference number if you already have one.
- The identity document or account holder details, since most South African providers verify who you are before discussing an account.
- Dates, amounts and any error message exactly as it appeared.
- A pen and paper for the reference number. Ask for one every time, because without it a follow up call starts from nothing.
Selling to the South African state
- Registration on the Central Supplier Database is free and done by the supplier. No consultant is required and nobody may charge you for it.
- Tenders are advertised publicly, on the eTenders portal and in the Government Tender Bulletin. Anyone claiming private access to an unadvertised opportunity is lying.
- Nobody can promise you an award. Bids are evaluated against published criteria by a committee, and a guaranteed tender for a fee is a fraud.
- Your tax and B-BBEE status must be current, and the CSD verifies tax compliance automatically against SARS. A lapsed status disqualifies a bid.
- Government must pay valid invoices within thirty days. Where it does not, the department’s supply chain unit and then the relevant treasury are the escalation route.
Keep the order number, the invoice number and the proof of delivery. Every payment query turns on those three, and a supplier who cannot produce them has no enquiry to make.
Complaints and escalation
If a first call does not resolve the matter, escalate through the company’s own published enquiry route. A listed company’s shareholder and governance matters go through the company secretary named in its annual report, and an ethics concern goes to the independently operated hotline the company publishes for that purpose.
Keep a short written log of each contact: the date, the channel you used, the name of the agent and the reference number. Most corporate complaint processes ask for exactly that history, and having it ready is usually the difference between a fast resolution and starting over.
Avoiding fake iOCO, formerly EOH contact numbers
Contact details for well known South African brands are a common target for impersonation. Numbers that look official appear in search ads, social media replies and cloned websites, and the person answering is not iOCO, formerly EOH.
- Reach iOCO, formerly EOH through the official site at ioco.tech rather than through a number in a search advert or a social media reply.
- IOCO, formerly EOH will never ask you for your full card number, PIN, CVV, online banking password or a one time PIN. Nobody legitimate needs those to help you.
- Treat any caller who creates urgency, asks you to install remote access software, or asks you to move money to a safe account as fraudulent, and end the call.
- If you are unsure whether a call was genuine, hang up and dial the official number yourself rather than calling back a number the caller gave you.

How do I know a iOCO, formerly EOH number is genuine?

What should I do if nobody resolves my query?
Ask for the complaint reference and the escalation path on your first call, then follow the escalation route described above. Keep the dates, agent names and reference numbers, because every formal complaint process will ask for them.
Can ContactDetails.co.za resolve this for me?

Is there a cost to calling these numbers?
South African 0860 and 0861 numbers are charged at a share-call or standard rate depending on your provider, and 0800 numbers are toll free from a landline. Calls from a mobile are billed at your own operator’s rate, so check your plan if cost matters.
