Problem with my balances and wrong information from consultant

<p>Good day</p> <p>I recently had a bad experience with one of the call centre agent.I called to query the problem with my account.I had airtime in morning and the remaining amo disappeared. The call center agent tells me that I used the airtime for internet and I explain to her that I have remaining data on my account so I couldn't have used airtime..I keep explaining to her that i am even checking the balance now with *111# and the vodacom app,it shows that i still have data remaining but airtime has been use and i didn't make a phone call today. The call center agent make me look stupid when i tell her am even looking at the balance as i speak to her... Thats bad attitude from her</p>
