Telkom order confirmation issues

<p>I completed an online order for a phone line on 03/07/2016, after which the online system said I would receiveda call during business hours in order to confirm the order.</p> <p> </p> <p>On 04/07/2016 I received a call from ********** (google tells me this is Telkom), I picked up and the call was immediately put down from the other end. I assumed I had taken too long to answer.</p> <p> </p> <p>Today on 05/07/2016 I received another call from that same number, it rang for a second or two and was put down before I could answer it. 5 minutes later the number called again, I answered immediately - I got silence for a few seconds and then on-hold music. After listening to the on-hold music for 7 minutes and 29 seconds (this being time that I should have been working) the call was suddenly ended from the other end.</p> <p> </p> <p>How am I to confirm an order if Telkom keeps putting the phone down on me? And why call me only to put me on hold for 7 and a half minutes (without any person greeting me or explaining the call), waisting my work time?</p>
