Payment plan issue and blilling

I am so disappointed in Multichoice,I have taken up a price lock plan with Dstv I have always had a debit order active with them,they have been debiting my account ever since my payment plan came to an end December/January my services have been always active and they have been debiting on my account I was debited on the 30th of September 2019 and they disconnected my services on the 7th of October I was informed that I was overdue for the month of may so I was back paying for May I stayed the whole of October without Dstv while they debited money on my bank account I then asked why would I be informed about an unpaid debit order of May in the month of September? They told me they don't know they will "escalate" to the billing department...When you call customers service for assistance you never get help they will only tel you that they will "Escalate"...Since well I back paid and stayed without servises the whole of October I was charged an "x" Amount money including reconnection fee for the month of November I made payment and my services got active as soon as I've made payment..I then get an Sms Today Morning on the 6th of November telling me that my services got disconnected I need to pay an "x" amount money plus reconnection fee and I have paid already I called in spoke to Thembi Goli who informed me that the is payment that is not appearing for July and they have been debiting me on my account the more I pay the more I owe and stay without Dstv at first I was told I was still active on a payment plan and it came to an end already when I always request to speak to a supervisor there is no supervisor assiting agent on such calls now I wonder how do they run a call center without any supervisor in place...The supervisor who was on Duty is Donald Ledwaba and he was no where to be found after speaking to an agent for a duration of 55:46 without any help....this is very bad service I am not happy at all I'm coming to a point where I feel like I can just take off all the decoders at my place and dish give them everything back and they should refund me my money!!!!! If we are not appreciated as Customers we might as well not care less
