Apalling

I bought the device with my car dealer in April 2019, device was installed [still in April] and on the same day I called the customer care to get my app log in details. In the process, it turned out that my names were mispelt which would have left me with an incorrect name/username and I refused to accept that [especially when the agent told me that they don't understand why I was crucifying them for what was no fault of theirs] until it was rectified. As if that was not bad enough an experience, months later I realized that my account has never been debited. I called today and only to be told that they don't have my bank account details. who was supposed to have ensured that you have my banking details? what would have happened if I did not notice that there has not been any debit orders since May? The service I have received from you thus far has been nothing but atrocious - I will be expected to part with 3 months worth of premiums in 1 debit just because of your incompetency. I don't need your apology as it is not going to be of any help to me at this stage. I am extremely livid - how do you run a business like this?
