Tracker Accounts nightmare

My account with tracker has been a mess for almost one year , with no sign of it being sorted out , even after visiting the nearest office ( round trip of 250 km's ) on three different occasions For 8 months they were charging me twice for the same vehicle at different rates , eventually received a refund , ( even after being refunded they continued to deduct twice , and i eventually i received another refund. They then changed my bank account details on there system , ( without any knowledge to me ) which results in the account payment being rejected by the bank and not being paid ( to make sure the account is paid i pay by EFT ) However i now want to cancel the contract , and was told by the call centre ( who are very poor at handling customer issues ) that the account has been cancelled , and i only need to pay the cancellation fee - however i now have three invoices raised against my account 1. The cancellation fee 2. Subscription for May 2025 3. Subscription for May 2025 with increased VAT After calling the call centre and being passed from one untrained person to another one , i decided to complete the online form for help - to no avail NO FEEDBACK , NO CALL BACK , NO HELP IN RESOLVING THIS ISSUE Can someone at tracker please HELPPPPPPPP
