Data gone without a trace!

It's been a while since I had issues with Vodacom. And it seems like they at back to their old tendencies again. On Saturday (10 October 2020) , I bought 1Gig data for both Saturday and Sunday for R29. I hardly used the data during the day, I would search an unfami**** word on Google then switch the data off again. In the evening, I decided to catch up on Facebook. It was not even an hour, but I noticed that it wasn't refreshing anymore. I sent a WhatsApp but it didn't go through. When I checked my balance, it didn't show that there was ever data, it only showed that my WhatsApp ticket had depleted, which I understood. Earlier on I had received confirmation that my 1Gig data was activated. I was surprised that my data was 'finished' because no SMS had come through to warm me that I had a certain amount of data left, none of thta came, so I'm surprised that the data was finished, just like that. I called their call centre at around 22h40. And spoke to a lady named Thobile, she said she was waiting for the system to update as she doesn't know what happened to my data. After a while she said she has escalated my complaint and I would get an SMS within 24 hours to confirm this. No SMS has come, I still don't know what happened to my data. Please refund me my data!
