Poor advertising,misleading from Telkom

I am a customer at telkom mobile. I purchased a internet data bundle for R49.50 and apparently it is divided into 12 months. I usually buy Free me boost however my bundles have depleted so I opted for internet bundle as it was affordable. My problem with telkom is this is poor and ********** way to advertise your bundles. When buying a free me boost on the options it does advertise that for 5gb or more you get free LIT bundles,however they fail to tell you that the data you purchasing is gonna be divided into 12 months. It also doesn't help that the client care line agents are rude and they never allow you to speak to management. I was told to "call" if I don't understand the bundle information. By an agent called Thando. While the first agent Katlego Radebe told me to restart my phone. I do want my R49.50 back so I can purchase another bundle. This is unacceptable. Your agents are rude and they know nothing about empathy towards client.
