Can I cancel an order? If I’m suspicious it may be lead to problems?

Hi! So I’m a fairly new Depop seller, my post was up for under 20 minutes and got sold by someone with a 2 week account, no profile pictures, no likes ect. From all the reviews and stuff I see from people saying disputing is hard I’m just nervous that they will try and scam me. I always take videos recording the shipping process ect. Is there a way I can cancel the order? I just honestly do not want to deal with getting scammed and going through Depop. The username is also just very sketchy.
