I went to Zaack gold exchange where my gold was weighed at around 20g less than what it really was, I took out my own scale and then showed them the correct weight. They then used another scale and then agreed on the correct weight. I then came to Gold Capital Illovo and met with the owner, Ran and received absolutely amazing service and advise. Thank you
