Telkom Bad service and poor internet service

I'm very angry with how Telkom treats us, firstly when calling you have to spend 20-30 mins at the IVR machine. I've been buying the Mo'Nice data bundles. All the time when I purchase the data my network switches from 3/4G TO H+. When you call in to the customer service they end up hanging up on you. I'm not pleased at all with I want my data that forfeited to be rembersed back
