20 gigs disappeared within 5 days

Hi guys.

What can I do? My telkom 40gig contract kicks in the 1st of every month. Since the 01/05/2019, I have downloaded maybe two presentations less than 2gigs. There is no one at home during the day and evenings my wife and I use the WiFi for browsing and the odd watching Facebook videos on our phone. YouTube video on phone was maximum for an hour since the 1st of May. Now I have 0Gb left. Telkom is telling me that I have used alot of Data when I know in actual fact that I have not done so at all. Any advice, or info that anyone can share I'd really appreciate.

Thanks

I only used my laptop twice to connect to the WiFi. And it's got windows 7 on it. When the laptop is not in use I unplug the ethernet cable

If you visit a Telkom shop they should be able to show you a log of the data use and the times which might help to determine what was downloaded.
