Finding a property owner

[Sipho Maodi]

Hi i have spotted a vandalized three bedroom house in Pretoria, took address and got a deed printout from the deeds office. The problem is i only got the property owners name and Id no. , what they paid and when they bought the property on the deed information printout. My question is how do i find the property owner with only the id no. and name, no cellphone number nothing? The property is in South Africa/ Gauteng in the city of Pretoria, Mamelodi to be precise.
