Lost data, poor service and cluelessness

I complained to Telkom about data losses. When I requested for a schedule of usage it didn't make sense and none of the call center agents could explain that to me. They opened a case for me to investigate but I am worried that I may be like one of the many customers who are suffering due to poor service and my unresolved manner.

If you are considering getting a Telkom data contract, I ask you to think twice and reconsider.

Can someone expose Telkom further.
