Hi, I had an interesting experience with MPesa on Saturday when I received a payment received notification with a deadline message as would happen with an unregistered recipient yet I am a registered user. My registered account did not register the transaction at all which was interesting. Being a law abiding citizen and client I called customer service, the person I spoke to as usual went off script to ask me all kinds of irrelevant questions such as do I have a dual SIM phone, was I expecting money from the person and when was my last transaction all of which are questions that do not assist in resolving my question. I sometimes wonder why I actual take the trouble yet all I should have done was gone to an mpesa agent and withdrew the money. As in the case of funds wrongly credited to a bank account I would have paid back the amount at my own rate. The error in this case was equivalent to me picking cash from the floor of the supermarket. I noted that the transaction has been reversed this morning still and the message still assumes that I am an unregistered recipient. It is my hope that Safaricom's technical team have identified and sealed the hole as its exploitation will open them up to money laundering charges.
