unhappy client

I took out a contract of which was less than R600 and it came with 2 devices, then took out insurance and they said it would be R90 for both devices. Now I am being charged over R1000 monthly.

MTN is just messing up as their statements are not even clear on what I am being billed for exactly. I am really unhappy and wish to cancel this ****** contract with them. When you call or go to the store, you do not get proper feedback. I am not happy at all
