Pathetic and very bad service

Hi I'm so ****ed with pathetic service that you get from cartrack on the 13th I called them to notify that I'm no longer working and asking for my debit date to be move from 25 to last day of month. I spoke to Bongani Hadebe were I specifically asked him that I want to speak to billing or credit department so I can make the arrangements he insisted on assisting me from client service department we continued were I informed him of my story that I'm no longer working so I won't be able to pay on 25 however I can pay on 31 so I also informed that I don't want my bank to charge me for any bounced debit since I won't have money on 25 he agreed later on 25 cartrack deducted money it was unpaid due to insufficient funds then they try again on 26 same story happened my bank charged me for unpaid debit R80 per unpaid. Then on 31 they debited it went through I then called cartrack again to query I spoke to the guy called Mpho he said he was a team leader I explained to what happened he never tried to assist me as well he told me that if I wanted to close my with car track it's a pleasure I can do that but I have to pay closing account fee I refused he then said he will ask someone from billing to call me back so I can sort it out with them that was the 10th of Feb 2020 till this day I'm still waiting for the call. I so hate cartrack it makes my life difficult for agents and team leaders they don't know what is customer experience is, team leaders there they don't know what is their tittle instead if a customer says they want to cancel the account they are will and gladly want to do that never minding that customers are the one that makes a brand or company please someone assist with this issue before I take it higher
