The verdict in three sentences
An instant, no-questions refund is an open invitation to friendly fraud and fake payment failures. In Johannesburg in 2026, a merchant who refunds only to the original wallet, after an order match and a 24-72h buffer, removes almost all abuse. The right trade-off is not to block honest buyers, but to add three controls that are invisible to them and off-putting to fraudsters.
The fraud patterns to know
Mobile-money refund fraud does not look like card theft. It exploits trust and speed. Here are the most common patterns (2026 order of magnitude).
| Pattern | How it works | Red flag | Estimated share |
|---|---|---|---|
| Fake failure | Buyer swears payment failed when it went through | Operator shows transaction confirmed | 30-40% of cases |
| Friendly fraud | Order received, then "not received" refund request | Delivery proof exists | 20-30% |
| Third-party wallet | Refund requested to a different number | Wallet differs from purchase | 10-15% |
| Double refund | Claim on two channels (chat + call) | Same order, two tickets | 8-12% |
| Repeat abuser | Same buyer, repeated refunds | 3+ refunds / 90 days | 5-10% |
On average, fraud is 1-4% of refunded volume; with no controls it quickly passes 5% and eats a store's whole margin.
Instant no-questions vs verified workflow
The "customer is king" reflex says refund now. Great for satisfaction, ruinous for fraud once volume grows.
| Criterion | Instant refund | Verified workflow |
|---|---|---|
| Customer delay | Immediate | 24-72h (published SLA) |
| Order verification | None | Mandatory match |
| Target wallet | Any | Original wallet only |
| Fraud rate | 4-8% | 0.5-1.5% |
| Support cost | Low upfront | Moderate but stable |
| Operator disputes | Frequent | Rare (evidence kept) |
| Margin impact | Silent erosion | Margin protected |
Key controls: order match (ID + amount + date), refund to original wallet, a 24-72h buffer, and a blocklist of repeat numbers (3+ refunds in 90 days).

Mini case study
Prosper runs a sneaker shop in Johannesburg, processing 600 orders a month at an average basket of 22,000 FCFA (about 34 EUR), or 13,200,000 FCFA in volume. With instant refunds he lost roughly 5% to fraud on refunds; refunds were 8% of volume (1,056,000 FCFA), of which 52,800 FCFA was pure monthly fraud. Switching to a verified workflow (48h delay, original wallet, blocklist) drops fraud to 1% of refunds, or 10,560 FCFA. Monthly saving: about 42,000 FCFA, over 500,000 FCFA a year, for three controls added at checkout.
FAQ
Won't a 48h delay frustrate my customers? No, if you display it clearly ("refund within 24-72h to your Wave/MTN wallet"). Transparency reassures more than a suspicious instant delay; honest buyers accept it, fraudsters give up.
Why refund only to the original wallet? Because 10-15% of attempts redirect money to a third party. Refunding the number that paid makes third-party-wallet fraud nearly impossible and documents the loop for the operator.
How do I spot a fake failure? Check the operator status: a "successful" transaction on Wave or MTN MoMo proves you were paid. Keep the reference and timestamp; only trigger a refund if the status is genuinely failed or unconfirmed.
What goes on a blocklist? The wallet number, not the name. Beyond 3 refunds in 90 days, require a manual check before any new refund. That focuses effort on the 5-10% of repeat abusers.
Do I need a special tool? A simple register linked to your orders is enough at first: order ID, wallet, amount, operator status, decision. Kolonell wires these controls straight into the e-commerce back office.
