Unblacklisting phone and Prepaid Sim activation

My account I***-6 was in arrears and my number was deactivated and my phone blacklisted. In February 2016 I managed to pay all the outstanding amounts and balance of contracts to the total amount of over R12 000 for Vodacom to cancel the contract and to unblacklist the phone and activate a new prepaid number since the other number I was told that it was recycled, The last payment I made was on the 29/02/2016 and now it's full month but still with no service. I was told that it would take a week, everytime I call the call centre there's no straight answer about my account. How can I pay so much money and get such bad service. This is totally unacceptable. I go to the branch they cannot help, I call the call centre they cannot help. This is unacceptable, period!
