Irate client - account handed over to legal with no prior notification!!!!

I have been a customer with Cell C for many years, but the service from customer care and legal is just shocking to say the least. I went in on the 27 of January to process my upgrade, only to be told - sorry you can't because one of the accounts was handed over to legal. I was shocked to say the least as I have had NO notification of anything being outstanding. I was informed by the salesman to contact the legal department via email and a contact number provided. I emailed with NO REPLY, the number keeps saying it has a technical error I must try again later, Needless to say I have been trying everyday with the same story - technical issue try again. I then called 140 after 3 failed attempts I was given a number ***, to call saying that they are handling the case. So I called the number only to be told no sorry they don't have the case. I then call 140 back fuming. No they don't understand the system shows they handling the case. Now irate - I called 140 again. They then give me *** they have the case, Just to be told no sorry the account is not with them either!!!! I notified the salesman at the store that this is what is happening. The next day I call 135 they tell me no the account is with Cell C legal department but says the account is owing almost R5000??? I am so confused, Who is dealing with this account??? When I called the legal department again -they say NO the account is back with Cell C. 1. How can an account be handed over without any notification? 2. Who the Hell is handling this account? 3. Why was I not notified that the account was handed over? 4. How did the account get to almost R5000? I made a payment of R1395 end September and was under the impression my friend was paying as the account actually is his although it is in my name hence no notification that the account was outstanding. (the account is R498 per month - End of October, November, December, January, and February = Total should then be R2490 if no payment was made) This account is separate from my other 3 contracts as it is link to my friends account. My 3 contracts are paid up to date.

I need to get to the bottom of this as soon as possible. Cell C has ruined my birthday. I am at my last straw with Cell C. It is ridiculous that NO emails back or gets back to a client!!!!
