poor customer service

The poor service special in after sale service, I send the car for a service on the 05/07/2021 it was due for oil change as well, I report slid sunroof failure, they only assist me with a service only she mention that, the sunroof we have to book for another day, we agree for a booking on 06/08/2021 then you loan me X3 for almost one week while my car in service, I collect my car as the sunroof problem was resolve, I try to open sunroof in two days later ,it fail to open. I report the problem. They book for 09/09/2021 they fail to fix problem since they was many things were reported need attention on the vehicle. They want the vehicle back on the 27/09/2021 so they can strip the whole sunroof to take photos for all physical damage, I sent the car on that date. It mean they are not doing the proper job for the first time. Course they call me again today want car back for check-up angina on the 06/10/2021. I was expect the call for fixing the sunroof not for the check-up now and gain. We trust you Kirsten Hodgson to resolve this, It ready give client frustration. special your competitors Audi and VW I own other vehicle from them, they have professional service and client recognition but BMW it like you selling cheep car, you forgot all the the time you dealing with executive client.
