Pathetic service from telkom on duplicate billing

Duplicate order, duplicate billing. reference ***4. STILL no assistance. duplicate sim should have been cancelled, now it is on my account. No on can help me, this is absolutely ridiculous. Since the 8th, I have been trying to resolve the sim cards received in triplicate. Do we really have to take legal action to get any kind of support or customer service from Telkom. PATHETIC
