Disappointing DSTV

Worst service I have recieved. Why is it that when ever I call in I always receive different amounts to pay, I'm extremely disappointed in the fact that I have had to call 3 times to sort our 1 problem and being on hold for 25 minutes and only for the call to drop. Now apparently I'm in arrears why wasn't I informed of this prior to payment day, consider me not paying it at all, I was also signed up for a service that I wasn't even aware of yet no documentation was sent to confirm my subscription I am beyond annoyed, furious and honestly I should swearing. Sort yourselves out and relay the correct information
