Hustles with settling Wonga account!

I have never been this confused with a company. I have a loan that I have been trying settle, but no one seems to help. When I login to my Wonga account I can see a balance of R940.38. I call the number provided on the wonga.co.za website (***) and I get through to a company called VVM. They tell me that they can't see an active account and that I should call Wonga directly. This is where I get confused, how does a number on the Wonga website go to another company? The only other number provided on the website is 086 968 424 doesn't even go through.

All I want to do is settle my account!
