Debit on no service is money laundering

So I have a tracker in my car with Netstar. On April 07. 2020 I realized upon looking at my statement that the alarm system is not working, there was no information. I sent an email to Netstar since getting to them through calls was a mission, no availability. End April, the debit went off again with no communiaction or feedback on my problem. I reversed the amount but Netstar was not being kind they debited what they thought is due to them. I complained on Facebook and they came back to me, I guess reputation is better than customer satisfaction. An agent checked my Alarm and she told me there is no response, she assured me that Nestar will refund me what was deducted from the time the alarm was not working to date, I guess they have taught their agents well since that was a pure lie again. They cancelled my subscription as requested and I got the confirmation, not that the was anything to cancel, the alarm was already not working and the technician never pitched to attend to my query. So come and June, no refund and Blissfull Netstar has debited my account again for no service. I am fustrated, disturbed by such a level of dishonesty and ill treating of customers. Maybe Netsar prefers debiting for no service. My account number is ***5... and my cell phone number is ***.
