I got a tracker on my car and tracker then didn’t debit their money as arranged, I then called tracker to find out what is the delay only for the the customer service agent to make a mockery of me. I repeatedly asked for her to atleast give me banking details so I can put my tracker up to date. Until the end of the call I never received help as to how to pay and put my account up to date. I’m still stuck on I don’t know how to pay when to pay why they are not debiting
