Terminal Covit Customer Care

I subscribed to Mega talk a month ago and on my first account appeared a charge for a pre-paid sim-card that was never activated. On my repeated requests to so-called "Customer Care" to rectify the matter, I trice received the response: "Kindly allow 3-5 working days for the ticket to be attended to." Twelve "working days" later the erroneous amount was deducted from my bank account, and I am still awaiting a response. "Customer Care" indeed!
