I need a balance

I have been calling your contact centre since last week to get a balance for the month of November, I was on contract until November and now I am on prepaid. When I called last week, I was told to call after the 5th of December, I called yesterday to get the balance so that I can make an EFT payment, no one could help, I was transferred to all departments including collections. I decided to give up, today I called the *** number and my call was transferred to cancelations department, cancelations department transferred me back to the *** number. I was told since I'm on prepaid on their side it shows 0. I need the balance so that I can settle the account, call me with a balance, don't bother to call if you don't have it.
