Disappointed by telkom

I have been using Telkom for a while now and thought it was the best network on this planet until recently; when I wanted to find out what their other prepaid tariff plans had to offer. Boy did I make a huge mistake. Little did I know that unlike Vodacom, Telkom only let's you change your tariff after 30 whole freaking days. I never had that issue with Vodacom and I could dabble with the tariff plans until I found one I was most comfortable with. All I had to do was wait a day. To make things worse I'm now stuck with a prepaid tariff plan for life. (Smartbroadband wireless prepaid). No warning is given when you make the tariff change on *180#...And top it all off, my airtime disappears from time to time without me even being connected to the internet or making calls. I was happy with Telkom, and all in month's time that changed. Moving back to my old network seems like a good option right now.
