Cartrack poor service

In November Cartrack debited me on the 28th Nov 2025 the usual premiums but then the next day again on the 29th November Cartrack double debited me morethan what we agreed on.i called and i was told my account is up to date and it shows that cartrack is owing me the money for my 2nd debit that happened on tje 29th, i asked for a refund they refused saying they do not refund anything less than 300 but then they will utilise the payment for December meaning in December they will not debit from my account but they will utilise the money..but i was shocked when in December they debited me ain, i then disputed the debit order, after that i received emails and sms's that my account is not up to date, but how? I also have proof from my statements.cartrack is failing me big time, from Nov till to date they are failing to give me a solution.i called million of times calling the accounts department but all of them say they dont know how to assist me, instead they say they have invoiced me or bouncing debit order..but how is it bouncing while they never utilised the money they over debited me? 3 days back they went again to debit n failed, yesterday again on the 23/01/26 they debited me again and still the money they have debited is morethan our agreed debit amount while the debit date is 27th each month.i have sent my query and emailed my query with proof from my bank statement and still no one answers me instead morw debit orders from Cartrack and they are not caring about customer service.since Nov till now it has not been attended
