Unfair trade more especially for disadvantaged individuals

Tracker wants to make two deductions in one month?..I have sold my old Car to garage in October 2024 and I was on a month to month or out of contract and now they want to deduct again for my new car, when I'm asking they said that money is forfeited coz is for notice period. How can I service a notice while I'm out of contract?. they are refusing to transfer those funds to my new car and they insist on debiting again more especially for a device that is not in my disposal. Tracker it's a **** what they know is to deduct our bank account and their recovery rate is way too low in comparison with other tracking companies
