Cartrack keeps on taking money three years after contract was cancelled!!!

Utterly disgusted with Cartrack! I have been a client from 2010 till 2016. I cancelled the contract in writing and telephonically as I do not have the vehicle anymore. Since 2016 Cartrack keeps on subtracting the debit order from my bank account. I called again, sent mails again for them to stop. Cartrack said they would. This is three years later and STILL Cartrack debits my account for a service I do not have! Is Cartrack going to reimburse me for my time spent to useless agents promising to stop the debit order? Is Cartrack going to reimburse me for all the calls I make to them to stop this issue? Will Cartrack reimburse me for all the banking costs incurred trying to reverse these debit orders? Will Cartrack reimburse me for travel to and from the bank, for time spent in ages at the bank, for the inconvenience? I doubt it!!! With how many ex-clients do you do this, pocketing the money month after month for no service you deliver and just wear them down so they eventually just get fed-up and you take their money! This is totally unacceptable! Cartrack will most probably just respond with their standard message and again do NOTHING! Except to just again debit me next month, AGAIN!? Three years this has been going on. Seriously?! Three years!!!! Stop your nonsense and bullying! Your admin sucks!!! You are taking money that does NOT become you, Cartrack! You are costing me money Cartrack. This constitutes theft in my books. Get your act together! Awaiting your response and a SPEEDY resolve. Not the empty promises of the past three years!
