Bad service - over promise under deliver

This is so upsetting for one to feel like you are paying for no service especially if you went out of your war to make sure that your affairs are in order, on the 24th i called netstar and advised them that i need to cancel my current vehicle and activate the new vehicle under my name and i was assured by two consultants the one who initially answered the phone promised she will see to it that my Haval policy is cancelled and the gentleman who activated my VW also then said i don't need to worry as he will also see to it that the policy is cancelled and that i won't need to pay a higher amount on the new vehicle as he would request that the debit order taken on the 20th be moved to the current active account which i was satisfied with, with no communication on the 2nd November i get a bank notification advising me that they debited my account what for i don't know as it's not even the amount for the new vehicle that's being debited and since when are my debit orders facilitated on the beginning of the month when my debit order is supposed to be scheduled on the 20th? what's frustrating is on the call i asked all these questions and was reassured that i do not have to worry i also noted that my account shows that i'm a company and not a private client and asked if this will not affect me when i have to claim or anything else and i was advised that i shouldn't not worry as soon as they VW reflects on my netstar account it will be rectified what service am i paying if people cannot simply hold their end of the promise how do i have confidence in you guys when something goes wrong if the service is so BAD??? i really do not like sending such communication but i am paying for a service after all i just need SERVICE!!!!! and now i had to reverse this amount as i did not understand what this is about, and my credit will be affected just because people don't care about customers.
