Airtime Balances expiry dates removed from My Vodacom app

The 'My Vodacom' app used to show when airtime balances were expiring. This was removed about a month ago and one is no longer able to see a breakdown of when airtime is expiring. I have tried to email to find this out, but vodacom has disabled the email service and only seems to want to have calls. I called to find out and the operator didn't answer my question at all and put the phone down on me. I am unhappy with this service and would like to know why it was removed from the app. I would also like to have a breakdown of when each amount of my airtime expires and ideally I would like to be able to have this available to help myself online or via your app
