Accounting mismanagement and poor customer service

On 29 September 2020 according to the info on My Vodacom, I had some 400 odd talk time left on my package, some 6Gb anytime data and some 400 sms's. Today 30 September 2020, according to the same My Vodacom app I have the same amount of talk time, 25 Gb anytime data and the same sms's as on the 29th September 2020. According to Vodacom my package contains 150min talk time, 2Gb anytime data and some sms's per month. I am trying to phone people urgently, however I keep getting a message that I don't have sufficient "airtime" available to make any calls??? Can someone at Vodacom please explain how this is possible when looking at my account?! What is the difference between "airtime" and "talk time" since there apparently seems to be a difference?! I'm any event, the balance/s reflected on my account according to the My Vodacom app is quite clearly incorrect and as a result I cannot conduct any business. I and anyone else cannot accept this situation and still try and continue to stay in touch with people and try and make a living with such obvious pathetic accounting and administrative mismanagement.
