Yesterday I bought 1

Yesterday I bought 1.3 GB of data and within 10 minutes it was depleted without me using it on anything and when I try to enquire their customer service number have no option to speak to a consultant and rather referred to their "Tobi" to communicate with which was not helpful at all. I tried again this morning to enquire and requested the breakdown of my data usage which they sent me and it showed that my Google meet app used 1.1GB and when I ask how because I was not even using the app by that time and I don't even know when last I used it, their Tobi has no answer for me, when I check my data usage on my Google meet app it does not say what they are saying it shows that for the past 30 days the app used only 729 KB. This is very unacceptable I can not buy data just for it to disappear like that even after I switched off my data.
