Dealing with cutoms resellers - "dawn tech" and "import world". Experience, scams, dos and donts

So im planning to pull the trigger on an rog ally x and 2 companies on olx have caught my eye - "Dawn electronics" and "import world".

I got in touch with both and called them they mentioned the same story that the sell products that got denied entry by customs etc hence the low price. Dawn does apparently have an actual store somewhere in east india while import world directly stated no f2f and 50% upfront. The pricing is too good to be true and ik it might be a scam but for the off chance its not please help me out!

I wanted to know if any of u have dealt w them before and if yes are they trust worthy shud i buy? Etc? This is a hail mary hoping someone has dealt with them before.
