Bad service and never will recommend

For more than a year I have been struggeling with Cartrack and my debit orders. Mrore than a year and multiple calls to get my debit order sorted out and still they cant do that. Get double debited then you have to wait 28 days to get the extra debited money back which they take in a few seconda. The ypu want to cancel because of bad service and you have to pay a cancelation fee because they are incompetant to sort out their issues. Why is it getting to be the cliemts responsibilty to pay for this kond of bad service. I WILL NOT RECOMMEND CARTRACK TO ANYONE. If you go to the bank you hear there is more people complaining about Cartrack. And Cartrack doesnt sort out their customers but just want money for their bad service. If the debit doesnt go through the day before the debit date ypu are paying banking charges and then they want to call you and tell you you arw in the wrong.Or they debit a day or two after the debit date and stil it is youre problem of the funds are not available. Again. Why should I pay a cancelation fee if the company are incompetant to sort out their services? Can anyone explain this to me?
