*********** staff at accounts department

My SIM is blocked and I don't owe Telkom a cent. I was told at 10:55am today that the line will be unblocked but still at 15:09 I called it was still blocked and a manger failed to talk me on the phone because he's too busy with other things. After I have explained that I use this line for business. I'm very infuriated by Telkom. I'm taking this further.
