Vodacom online shopping

Vodacom flagged my number as *****ulent after I made an online application for a double-deal phone contract. The call center picked up that I was now using a different surname, and they requested that I go to the Vodafone branch to submit supporting documents. I went to New Market Vodacom to submit the documents. I am very disappointed. Why did they ask me to provide supporting documents and then flag me as a *****ster? I just do not understand how changing a surname is a crime. I want this mess to be rectified. If they did not want me to apply, they could have declined the application instead of messing up my credit profile with false information. I understand that new customers are not valued, and even their customer care did not even bother to call me to find out more about my complaint. I logged a complaint on the 18th Vodacom Customer ***, but to this day no response has been received.
