Refuse to give me feedback on my case

Telkom double debited me for the second time in one year. After constanstly calling almost a month nobody ever gets back to me. Call centre is useless. They blatantly tell u they cannot help u. I need my refund urgently! But they just dont seem to give a damn that they have put me in such a rough spot. My other debits did not go off because they double debited me and i have mounting charges to pay. U truly run the worst service.
