Poor customer service, not getting updates regarding my car that was booked in.

I took my car in for a turbo actuator issue on Tuesday the 29th of April 2025. The last update I got regarding the car was on Friday the 2nd of May 2025 only when my brother went to the dealership physically to get an update from the service advisor (Siya). The last update from Siya was an indication that parts have been ordered and that the car would be worked on and done this week. On every occasion when we try getting hold of the service advisor (Siya), we never get answered. Today on the 5th of May 2025, I tried to call but could not get hold of him. I ended up passing my message to the reception but never got a call back. This is poor service, service advisors from other VW dealerships I have worked with ( for example Autohaus Centurion) are responsive and provide updates on vehicles they work on. This is poor customer service from VW NTT East London, I expected better and currently do not have a car.
