Very poor service

I am so angry, I paid for the services on the 7th of July, I paid R500, R450 was for the channels and R50 for reconnection fee. My services were disconnected on the 14th of July. I called the customer service and I spoke to Ayanda Nonzipho, she told me that i am owing multichoice, I have two decoders and I was charged fees on the other one as it was not cancelled. I explained to her that I cancelled the first decoder early last year when I bought the new one, she said it was hidden not cancelled. Last year in August I had to pay more as I was told my first decoder was not cancelled and there were charges. I was shocked that I need to pay another amount for the same issue. I asked the agent to escalate the matter to her team leader and ask the team leader to call me, no one called me. I called again later and the gentleman assisted me by opening my channels. On the 17th it was disconnected again when I called the agent by the name of Nosiviwe Ngxeke told me I am owing multichoice becuase I paid on the 7th instead of paying on the 9th I was cherged the Pro rata and I needed to pay before they open my channels, she was very rude, I tried explaining my query but she kept on saying she can't assist me, i asked her to check my account, she told she's working from home and can only check account till March, I asked to speak to team leader she told me I can't and she dropped the call on me. I PAID ON 7TH AND IT WAS DISCONNECTED ON 17TH MEANING I PAID R500 FOR 10 DAYS, can the finance department check my payment records from last year and fix my account please I am tored of fighting with agents who do not know what they are doing, multichoice customer service is very poor, the agents do not care about the customers and that will make us stop paying for the services.
