Scammer send an SMS message phishing as from Singpost. The sms message showed up in the same SMS thread as Singpost messaging. The SMS message: "your parcel has been redirected to your local post office branch due to an unpaid delivery fee. Visit here: https://bit.ly/3geqbw8" (NOTE: Phishing link. Do NOT click)

This will link you to scammer's website that requests you to input your credit card number and all personal details, which obviously is a scam.

Be careful:
1) do not click any unknown link.
2) do not reveal personal or credit card details.
3) do not pay for things you did not order.
