Reliance Jio Infocomm — always shows wrong data usage

I have activated my new plan on 9th march where i get 6gb data for 3months. I have stayed home from 18th march due to the covid-19 crisis and have been operating on my wifi and not using my mobile data. And on the days i was working, i don't consumer my data more as i am always busy with my patients. Yet yesterday i received a message of consumption of more than 50% of my data showing the usage even when i haven't been using. I am really disappointed with this and my friends too have the same issue. And this is not the first time i am facing this problem and hence thought of approaching this time.
