harassment unprofessional provider sies

horrible service I have ever had with this company , now you tell me who is wrong here, I sold my vehicle in Aug 2020 and called then to have installation in my new car and removed device in prev car, they made me complete a from that I sent back and they kept quiet, in Sept seeing they not saying anything not even responding to my emails I reversed their debit order and guess what they responded with excuses of account being in arrears so they cannot assist me when in need I asked them to remove tracker they still didn't now they debit difference amount off my account I still reverse it , so I want this to be cancelled they want me to pay 2258 rand , they messed up by we the clients my suffer their inconsistency. I can happy pay your cancelation fee 1700 send me the letter but I'm taking this to consumer commission anyway. ******* provider you people. you can go back to all communication I sent you , I was the one making the effort to resolve this, however your *********** agents also didn't make it any easy
