My line disconnected and paid it in full and NO assistance to open line

I paid a line that had an outstanding amount and I was informed that my line will be activated within 24hours after settlement of arreas. It is now 5 days later and my line is disconnected, when I call 082135 I only get directed to Tobi who says he cannot recognize the number and cannot help and I automatically get disconnected. Can someone please assist me to open my number? It is such a frustrating process to deal with AI that doesn't have the full capability of handling various queries.
