Vodacom Legal department failing both customers and employees

Vodacom legal department is NOT cooperative. My account has been handed over to the network's legal department for a while and I've been trying to get a breakdown of the amount that they suggest I owe. I've been going back and forth and they keep making me jump through hoops just to get a simple statement to verify why my account went from +-R4000 to +-R21000. The Mimosa branch people people has really tried all they could to access my account but it's impossible for them since it's with their legal department. I would really like to settle this account once and for all but vodacom legal is making this process very difficult for me.
