Vague and unhelpful service

I usually don't have any issues with rain but lately, data just disappears. on 14/10/2019 at 6:30 ish PM I loaded data on my account.

Before switching on my pc went out to grab some food that took about an hour, then when I tried to go on the Net rain sent me a mail that I reached my data limit. Furious I went onto the website and on the dashboard lo and behold the data I put on disappeared. when I went to check my usage it said I didn't even use 0.009GB of data today.

Then when I tried enquiring about it the consultant was vague and unclear with his answers.

This is becoming an ever-growing issue and if this continues I think that a local service provider or even Telkom would be a better idea.
