I got scammed on my first time trying to sell an item on carousell.

The fake buyer contacted me in the app almost immediately after i post the product ($20 necklaces). They said they want to purchase but will need my email and phone number to proceed. As a first time seller, i didn’t know it was the begin of a scam. I provided the details then, right after that I received an email saying the purchase was made successfully and it look very professional, just like a legit carousell email. I proceed on clicking the button "confirm order" and got redirect to a order tracking page where i have to input my card details. I thought it was normal to input my card details there just like how i usually make online payment, however it is not. In the form, they also ask for my card balance, i was doubting for a moment, but the fake buyer keep pushing me and told me they have already paid but why i can’t confirm them. I didn’t realize in that second, i just don’t want people to worry, and quickly key in all the required information in that form (including card number, date of expiry, cvv, card balance, and ended up with otp).

I’m sharing my story here hoping that no one would ever be a victim of this scam anymore. I don’t know why people would do this to each other. I have my lesson, please don’t be like me..
