I’ve seen a couple of posts lately about people pretending that they’ve “accidentally” sent money to people via M-Paisa and then calling them asking them to send it back when really, the victim is just sending money out of their own pocket because no money has been deposited in the first place.
If you’re getting it from a normal mobile number (+6799******) then that’s just a copied and pasted message.
If you have M-Paisa, be careful about who you give your details to and don’t, under any condition, give your OTP or Pin number.
