Disappearance of Airtime and Data

I think Vodacom is out to gather money from their clients to pay the Please Call Me inventor as my airtime and data just disappeared again. I saw the network dropping a few times today but havent put any thought into this, until I realised my data and airtime disappeared. I loaded 1G of data on 29 January 2019, which lasts me usually up till the 25th or so of the next month. I also got my monthly airtime for the contract value on the 1st, which is also gone. Quite impossible to use up all of this in the amount of time it got loaded till the time it disappeared. I am not using my phone as a hotspot or anything and use the LAN internet throughout the day. Kindly rectify this, or I will get the necessary authorities to look into this and investigate
