Poor service and frustrating different explanations from cartrack

I don’t even know where to start, the debit order thing with cartrack. The frustrating part is they debit different amounts of money, the create different debit codes, and constantly have to explain to them that one didn’t miss a payment. The force you to agree that you missed a payment, they lock debit orders in your bank. Am frustrated don’t know what to do anymore. The amounts of calls from them are so overwhelming and the more you explain the more it’s like you are trying to work yourself from the situation.
