No clear terms and conditions

The consultants and supervisors promise call backs but don’t follow up. The Payment system for Rain is messed up. How do you pay for a month you didn’t request the rain to be on , I thought it’s a month to month contract, pay then use. Like dstv, if you don’t pay it switches off then you pay for the month you would like to use the service. But rain charges you for every month even when you didn’t pay the month you actually want to use it you have to pay for all the previous months. No response from the complaints team for days and days now
