Kenyan telecom company Safaricom has released guidance on what M-Pesa users should do when a pay bill payment is sent to the wrong business number. The clarification emerged from an exchange on X between Safaricom Care and a customer, in which the company laid out the official steps for handling erroneous pay bill transfers. Safaricom confirmed it has no authority to reverse a Pay Bill transaction on its own.
Because funds sent via Pay Bill land directly in the merchant's account, any refund requires that business to authorise and process the return. Safaricom Care wrote in the post, "For the reversal of the pay bill transaction, kindly contact the organisation for assistance." However, many customers do not have the merchant's phone number readily available. This is where Safaricom's lesser-known shortcode comes in.
Safaricom's solution is to forward the original M-Pesa confirmation SMS to the shortcode **456**, which returns the organisation's contact details. In the case cited in the exchange, Safaricom directed the customer to call the recipient, noting that standard calling rates apply. This service can help customers track down merchant contact details when a dispute arises.
Safaricom also highlighted Zuri, its AI-powered virtual assistant, as an additional resource for customers stuck in a payment dispute. Zuri is accessible through its app, WhatsApp, and the Safaricom website and can help users locate merchant information, follow up on transactions, and navigate the formal dispute process.
Where Zuri cannot resolve an issue directly, the assistant escalates the case to a human agent. The broader advisory underlines two habits Safaricom wants customers to adopt. First, always verify both the pay bill number and the account reference before confirming a transfer. This can help prevent erroneous transactions.
Second, avoid deleting M-Pesa confirmation messages immediately after receiving them, as that SMS is the key to unlocking merchant contact details via the 456 shortcode if anything goes wrong. For businesses operating on Pay Bill, the guidance is a reminder that having accessible and responsive customer service channels is not just good practice but a practical necessity.
Given that any refund is entirely dependent on the merchant's willingness and speed in processing it, businesses must be prepared to handle customer inquiries and resolve disputes promptly. Safaricom's guidance aims to empower customers to take control of erroneous transactions and facilitate swift resolutions. The company published the advisory on 3 Nov 2026 at 4:37 PM.
