Samsung — replaced product in warranty period are damaged inside

I purchase samsung level u on 11/11/19 and in july 2020 it started facing problem of getting disconnected automatically, so i visited near authorised service centre of samsung in mehsana, gujarat. They told me that it will be get replaced because the product is in full warranty, but after 4 days when i got replaced product, it was broken from inside and watching it condition it seems that the product was refurbished and i gave it back to service centre than they started telling that it is in good condition it can not be get replaced but some how i tried and convience them to get replaced but the same story repeats i got another product damaged to it was full of skretches and wire of ear piece are crack. Samsung is provind refurbished product when you go to replaced your original product in warranty period.
