data depleted during load shedding.

On the 13th october my house had no power because of load shedding. Which meant i was offline and had no wifi. However the afrihost app shows data being used from my account. This means that data is being ****** even though i am not online. I have emailed afrihost numerous times with screenshots showing their app using my data even tho i'm offline without any success. I have also seen 22gig of data depleted over a few days. They say it's my usage of gaming, video calls, skype and teams. None of which i use. My data is being ****** and they don't seem to care in the least.
