Worst Service From Vodacom Ever

I recently app**** for an online contract where I did everything required and even got an email saying that If I don't hear anything from Vodacom in 24 hours I must call them where I waited and after no response I called the customer care line, you stay on hold for more than 10 min to speak to an agent and when the call was answered I got told that the application is still being accessed I must wait someone will call me, from Friday to Monday no contact from Vodacom where I then called again and got told the same thing that nothing is happening and that I must wait for someone to call me where I asked that escalate the matter and the controller I spoke to said she will get back to me, this is now 3 days after I app**** with no response or feedback from Vodacom where I continually need to call and still get the same answer wait someone will call you

How long do I have to wait for someone to call me and tell me what is going on?
