Incorrect Information given

I have been a loyal customer of Multi Choice for years now, and I have never experienced what I have experienced today. I have had an account with you guys with extra view which I use to pay R 450, I then moved out of home and stay at my own place, I then installed another decoder where I stay and cancelled ONLY the extra view at my parents place. The guy came and did the installation everything was perfect , I then spoke to one of your Call Centre agent's Sibusiso on the 4th January 2018 who clearly advised me that all of this will be done and my new installment will be R 815 altogether, however nowhere in our conversation did he advise me of pro-rata payment that needs to be paid. This morning I woke up to a call from my mother advising me that they have disconnected her decoder, I then called the Call Centre and spoke to Eufika and she advised me that decoder was disconnected because of non-payment , I was confused because I am expecting a debit of R815 on the 25th January as I was advised. I did not receive any sms advising of payment to be made, no notification none-whatsoever so since I pay via debit order, please advise me how was I supposed to be advised of this?? is this how you guys treat your customers, we must just guess that we must pay this amount? really I am so disappointed, had I known of this amount to be paid trust me I would have paid it or made a plan to rather have my decoder installed month end, this has really caused a turmoil between me and my mother. Please can someone listen to that call and tell me when was I advised of a payment that I needed to make
