Worst customer experience

I am not happy with multi choice, I had an agreement with them to pay R450 for them to reconnect my services, which I did pay and my service was reconnected for 4 days only, now they have disconnected me again and they say I must pay R1227. First of all I did not sign up for their insurance services, their call center agent signed me up for insurance without my consent. I am sick and tired because everyday I have to contact multi choice and they keep playing me like a fool. They don't treat customers with respect, it's been over 4 months now and I am not getting any help.
