My name is Lydia aupadia mukudza I was going to south africa last week when I got to the south african side they told me that my passport have a fake stamp and then they took two of my passports of which one of it was my daughter so is my passports going to be blacklisted or what??

Sounds like that is what will happen. Did they tell you anything else? Did they let you enter... or did they turn you back?

So where they fake stamps ?

You will need to contact your nation where the passport was issued.
