Struggling with cellphone contract application

Sales services are extremly poor. It took me 30minutes to complete an online application for a new cellphone contract on 06/05/2018 , just to find out it did not go through , but the webpage said it was an successful application. Nobody ever called me by 08/05/2018 (all of this while I'm borrowing someone elses phone just so I can answer the call from Vodacom). So I called them. So the sales agent says she'll help me with a new application , but when I ask her for information , she was very impatient with me , I had to ask her to repeat what she had said a couple of times because she could not slow down. So she needed my bank statements and so forth and said that when she had recieved them from me , that she would call me back. So I sent everything to her. That was yesterday , and I am still waiting for her call. I even phoned the call center again today and another agent informed me that my applications been approved , the original agent who helped me only needs to confirm my order with me , and they said they would tell her to call me but no luck so far. . By this rate I dont even want to take the contract by them anymore. I'm stuck without a mobile device of my own , and they are taking their good time about it...
