Bad attitude and disappearinf data

This rating is a lot.

I suddenly noticed that my data has been disappearing today. I loaded 4 gigabytes and within 30 minutes it had disappeared. I tried to contact their customers services I couldn't reach an agent. I then sent an DM on X. Yoh, the response I got from Vodacom is disappointing. The person I was chatting sounded annoyed and she/he was so passive. My concerns were never addressed. I wish I can post the screenshots of our conversation here. It is shocking that a big corporate like Vodacom will have such passive aggressive people as their ambassadors. Can I have an explanation how come my data is disappearing and also why I am suddenly being billed out of data bundles.
