Bad service from Accounts Department

Can someone in the accounts department please call me and sort out my query, car track debited my account on the 25th of June an amount of R580 for the new device that they installed in my vehicle, however they cannot allocate that amount, they keep on calling me and sending me WhatsApp msgs, which I have send them countless statements that confirm they did debit they however not allocating that amount, we go through the same thing everyday but nothing is being done, they refuse to allocate the funds so that means they *****ing from me a full amount of R580, they acknowledge the money but not allocating it, spoke to a guy by the name of Mabitle, spoke to Boitumelo, spoke to Zama but they not getting the account department to allocate tge funds

Can someone please assist me or they come take back the device since it's faulty and reverse my R580
