Rude call centre agent

I just received a call from the call centre agent to tell me about the wi-fi router. I then asked her to call me on my other number, which she did. I was still explaining my requirements to her and I told her that I would look into a new contract when my current contract with vodacom has ended. She was so rude and she hung up the phone while I was still speaking to her. Vodacom, investigate who I was speaking to and give me assurance that this person has been delt with appropriately. I need feedback on this matter.
