Clueless agent

So last night vodacom sent me an sms saying that I have less than 13MBs so I quickly bought the 1GB for a hour the time was 23:22 didn't receive a message confirming my purchase so I decided to check on my balances just to see if I still have my airtime & if the GB is there, I checked & it was there it even stated that it will forfeit at 00:22 I started using my instagram checking feeds there then 00:20 I switched off my data put my phone on the charger then in the morning I bought power combo for R12 now I just came home from work to find out that I have R22 something on my balance so I called vodacom to enquire about my airtime got a clueless agent & she claims I was on the internet past 12 & I confirmed she said to me my data forfeited at 00:00 of which is bull coz it was supposed to forfeit at 00:22 Zinhle says I didn't have data & I was using the internet so it was deducting from my airtime I told her that's impossible & asked her to let me speak to her team leader coz she doesn't understand my query & she said she is the team leader now I ask myself if vodacom can hire clueless people like her how are going to get help? All I want now is my airtime then I'll be fine. From R79 to R22?? That's a ripoff ngekhe vodacom FIX THIS I WANT MY AIRTIME
