Bad customer service

I have experience terrible customer service from Cell C contract /legal department. Customer service said I have an existing account that is now with legal. So for over 2months now I am trying to get hold of the legal department to assist me. And all I ever do is to hold till the airtime is finished because this is a chargeable number. All I need is the information regarding the cellphone contract "I have " with them. Worse part I am told that this goes back to 2009, I mean really for all these years no one has contacted me regarding this. Because all dealings I had with Cell C was all paid up. The call centre can't even provide me with a ref number for this account or for the calls. I don't know the cellphone for this account

What I need now, is for someone to contact me with the correct information as to how am I owing them, How much am I owing them? How do I make payments towards this account.
