Data still Missing

I am extremely upset with Vodacom and how my data just dissapeared within seconds. I called Vodacom on several times of which i almost gave up on 17th April 2020. I called from the beginning of April when i saw that my new data of 20gig day and 20 night has not been added to question them with no luck of getting hold of Vodacom. I understand we all under lockdown but this was too strange. The lady at the call centre told me that i have depleted my data and that they have added the new month which i cannot see on my side. I ask her to send me proof to show when the data was depleted and when they added the new months data. So she send me an itemised billing of which does not show data being added or depleted. I took screenshots through the month to see when will they add it. I still want to know what happened to my new data bundle i had to get on 1 April as my data just carried on from the previous month. So tonight 30 April 2020 I go into the Vodacom app again 1 second i had 31.86 mb left and next second all gone and my night data still on 25.14GB. So now i want to see if i will have 20g for day and 40g for night which did not happen in April and i feel i was being ****** since i did not see the difference on the app from March to April. You owe me 40gig for April still.
