Still awaiting feedback

I called Vodacom Call centre on the 06.08.2015 at 14:07. I got a bad customer service from the agent who first told me that the system is not showing anything regarding my airtime deduction, when she couldn't answer any more questions from me, she then decided to hung up on me. I then called back to speak to the Team Leader(Zakhele) who also wasn't helpful as he told me that he can only listen to the call after 24 hours and therefore he couldn't help me either. The agent was rude towards me and my query was left unresolved by the agent as well as the team leader. He told me that someone would get back to me after 24 hours, no one has contacted me back. I still haven't received any feedback regarding my query. The level of service from Vodacom was very appalling
