Money Scam

i was scrolling on tiktok and saw a really expensive arcylic markers that work really well so i bought it using my debit card but then a few days later the seller DM'd me and said that the markers are out of stock,i didnt belive them so i checked the product, reloaded the app but it was in stock so i confronted the seller and told them to refund me if it was really out of stock but after that they stope replying..... the total of the markers were around 35 ringgit because i bought the big set.in the end I never got my stuff or money...
