Poor customer service

I called into Vodacom this morning for assistance with a network issue I am experiencing. I am not able to send SMS's, when I try to, they bounce back. The first consultant I spoke to said there were settings which were not active on my number and that she has activated them and I should restart my device. She said she would phone me back to check if the SMS's had been sent, she has not. I then phoned back and spoke to another lady by the name of Sharon, as I was explaining the scenario she hung up on me. Please resolve my issue and educate staff on phone etiquette and customer service. It is extremely frustrating to have half a service on a network I have been using for over 15 years.
