Harassment of Ex-Client through Endless Debits of their Account

ConnectTracker or Tracker...thrives on ignoring cancellation notices, by Debiting for No Services rendered. In August 2022, I notified Connect Tracker or Tracker that due to my elderly status and doing limited driving (reduced risk), as well as limited income, I cancelled their service. However, despite the mutual agreement of cancellation reached, the company in question has simply ignored our agreement. It continues with monthly debits, doubling and trippling them at times. No matter how many times I keep on reminding them, all of my efforts are ignored. If this is not bullying by Co against the elderly, than I do not know better!
