DATA IS DISSAPPEARING

I received my rain LTE device on the 5th of December 2017. i went home at 16:00 at about 17:00 I set it up and went out. no one else was at home. When i checked the next morning on my data usage, it had used 9 gb, which is totally impossible.

i sent an online chat and the person who helped me, told me they could see there was a problem and he had all my details, and he would come back to me as to what they were going to do. (i am still waiting)

since then daily i have on line chats with call centre, one tells me its the right, the other tells me that there is a problem with the client zone and they working on it. there is a serious problem, i have broadband with afrihost which is now coming to and end, I have never used so much data as what i am using now.

i am getting no where.
