Telkom ***** , incompetence and customer attack

I have been humiliated and ridiculed by call centre agents twice this month for querying my data multi sim card account that registered depleted just two days after the start of the month. I asked for the "Call detail records" and it clearly shows discrepancies where one SIM card is charged 3 times at the same overlapping time. When I tried to ask the agents they got rude and even dropped the phone on me. Today at @3:52 where I spent 41 minutes and she dropped my call, o the first week of Feb was even worse.
