The Hi Mum Whatsapp Scam Message
If you get messages like the one above, the first thing you should do is call your child using the telephone number you have for him/her and confirm whether the message is true or not. If you are unable to get your child using the telephone number you have, tell the WhatsApp user to give you a telephone number that you can contact him/her at. If they refuse, it is a scam.
Never rush to send money after receiving a suspicious message or call. It is always important to calmly investigate or research the matter first.
