Contract problems

Good day, I have started my application at Woodlands Boulevard Vodacom in November 2017. I needed to take my phone number off my mom's account and into my own name. The documentation was handed in accordingly and she signed it off for the transfer. I was approved and asked to send banking etc. Nothing happened although I was told I will be notifed. 2 Weeks later I went in again and was told that I needed to submit my Credit report from Credit Union? This has never been asked for but I printed it and it was submitted (credit report is clear). After a week I still did not receive anything and again went back and was told that they are working on it (Now December). I was told that my account will be sorted out before closing on 22 December. I am now a month over and still no results. They claim bad payment but I have never had an account with Vodacom, I have had my number on my mom's phone since I can remember and Pay as you go in between when I was in the United States. Then my sister's number was still also on. Please can someone resolve this issue as it is becoming tardy and the buck keeps on being passed on from Woodhill to I don't know who at Vodacom yet when I call customer care they can find no application or any details regarding this account.
