Vodacom I’m disappointed

I’ve never had any issues with the vodacom network service but I highly disappointed in the service I have I recently received in the past two days I have a cell contract with them so my account was in arrears for 2 to 3 months and my phone was suspended after settling the account I expected to be credited my contract airtime I was rudely to told by the adviser I was paying for what I used for crying out loud the phone was suspended i wasn’t getting any service ,I was told if I don’t understand I should find the nearest outlet , when I asked to speak to someone that can help me understand (management) I couldn’t ,the famous contact center line was used “managers are in a meeting “ then laughed at before I can end the call by the adviser ,she clearly forgot to mute the phone .
