TELKOM *****ING MY DATA

Telkom Wi-Fi router is *****ing my data. Last week Friday I bought 10GB of data and streamed videos on my phone, woke up the next morning, with 17 bytes left. Again last night I bought 5GB of data and in less than 2 hrs with my phone on the charger so it's not even being used, the data was gone. How is this possible?? I've been trying to connect to the mobile app with my mobile data and it keeps giving me an error that it can't verify that I'm human. I'm very upset cause this month I've used up to 50GB of data when on average I use 15GB to 20GB at most. And I'm looking for a detailed usage statement on the app which now I can't access! This is ridiculous
