Telkom I'm very disappointed

I'm extremely dissatisfied and disappointed in the service of Telkom concerning methods of getting into contact with them. As soon as it was time for me to upgrade, 3 different agents would call me per day. Their Cape Gate store in Telkom has a number found on Google, which is unavailable for two days is questionable. I was told it's a walk in store, therefore it would be better for me to go in. This is a cellphone service provider.... Why is there a answering machine operator and no human behind the phone to assist a customer? It's been 3 days that I've been unable to speak to a consultant
