Utterly disappointed customer

The staff including the supervisor Darcus slides not understand the meaning of customer service. My son was standing in a queue made up of two people. He stood in the queue for 35 minutes waiting to be assisted while there were 3 other staff members sitting across the counter doing nothing. When I enquired why does it take so long to be assisted, the response received that there was only one person dealing with cash purchases-my understanding that paying by card or cash is a cash purchase. It is very difficult to understand that Telkom will only have one person dealing with cash transaction in a business that should be technologically advanced. When I asked to speak to the manager I was was referred to Darcus whose attitude needs to be reviewed by the senior management team at Telkom. She chose to argue with me with no sound bases rather assist me. I will definitely be canceling my service with Telkom both my ADSL & Mobile service with Telkom and move my service to a service provider who understands and values customers
