Unhappy client

My name is MJ Serobanyane a week ago I contacted this business because the service for my car was due and it is my first time to use their service. I received a confirmation to go ahead with the service though at first I was told that I need to pay two premiums which were behind if I still can recall the one was for March 2023 but I rep**** by saying I did not remember being behind.For normal circumstances if I was behind indeed why they took so long because I have a debit order in place or if may be there no funds why they did not inform their client. Today I took the car for service I was not help because they needed to know whether they will receive their payment after the service if not my car will not be released. I went back and called MVIA INSURE ,they told me to send the itemized quotation I send it round past eleven (11) but until now I have not receive it.I wonder how many elderly people like me who are going through this.If possible how about refunding my money so that I can arrange for my service.
