********** account opened in my name

I found out someone had opened an account on my name, however I don't live in SA anymore. The customer service members were actually quite helpful in steering me in the right direction, but once I had sent an email to the ***** department as advised, they just did not reply. I'm assuming it takes time to investigate these claims, but an acknowledgement of my email would be a good start. I am also concerned how someone can just open an account in my name without proof of who they are. Are there not enough security checks? I have registered with the SA ***** prevention service in the past. You would think companies would do more to combat ********** accounts and work with these organisations.
