Reliance Jio Infocomm — data exhausted automatically

Address: Nagpur, Maharashtra, 440032

My data got exhausted and i didn't even use that data. I don't know why but this is happening with me in between 12.45am to 1.30am. Jio automatically exhausts my data for no such reason and this is very disturbing and disgusting. It is showing that i've used 1gb of data at 1.10am. Well i didn't download anything neither do i watched online video, i used whatsapp only that too without downloading then how in the world my data got consumed? I've lodged complaints so many times regarding this but i want a proper solution now but each time these people not resolving & give all excuses that its only due to us.
