Waste of time

I spent 15 minutes on the phone with an agent about the atrocious 4G signal strength in my house. I had to spell out my name, address and phone number repeatedly letter by letter and number by number. I swear this person was close to illiterate so I’m not sure why they’re in a customer service department at Vodacom. He promised that SMS would be sent with instructions on how to choose the correct network yet not one of the menu items he told me about do not exist on Apple iPhones and the network that is supposedly Vodacom 4G does not exist either. He was also going to send me the ticket number for the service request. I have received no SMS whatsoever and no promised phone call either. What a useless waste of my time, effort and frustration to achieve absolutely nothing.....
