Bad service on cartrack account

Since November 2021 I struggle with cartrack to get a contract from them which they said I have signed and never received one they deducted 3 different amounts from my bank account R129/R310/R169 all on one car then they keep harassing me to pay my accounts as this is a new car that I have bought I don’t know who put all 3 of this cartrack things in as it was not me , cartrack send me a contract from a male person with the voice conversation he made payment arrangements for the R310 as I blocked his deduction from my bank account I have received mail which he wrote to cartrack as they want to blaclisted him from not paying his account. On my previous complaint I have posted cartrack said they will resolve my problem (still nothing is resolved) No contact/money go off my account / what type of people did you employed? I believe you wouldn’t know which 3 accounts to chase if my car get ******.
