Vodacom services & no response

This is my 3de complaint of Vodacom and still I have not received any feedback from them they only send me a email to say they can't get hold of me reference nr. EC-1KPO-3LJZ66. They are the only ones that can connect my service to get hold of me, that is not rocket science. What must I do that they can phone me? Here is my first complaint: (I have a complaint about Vodacom, Vodacom has cut me off from my services (incoming and phoning services) because I owe them money. I have spoken to them about my account and I have made a arrangement with them to pay them off (R100) a month. Because I am unemployed and have no income and I have to borrow money to pay them off. The result of them cutting me off I can not find work because you need a contact nr to do so and me not finding work I can't pay them. I know I owe them money and I'm prepared to pay them back. But I need my service on to apply for jobs. My hands are tide!!! And I am desperate to find work. So I want to know what am I to do? Can someone please help me?)
