Telkom is a ****

I have a unlimited data package with Telkom last month. Last month I was double debited upon getting to the store I was told I "subscribed" to something. This month I was debited 4times the amount....AYBO is it because they see my salary or what's happening? I REFUSE TO PAY R1800 for something we both agreed I'd pay R400.

Telkom is a ****!!!!!
