Pathetic Service

I would like to lodge a complaint. On the 11 August 2021 I called your VW Contact Centre to book my car for service. The consultant took down the details and advise that I will receive a call from the dealership regrading the booking. On the same day the VW sent an sms to confirm the booking ,then later that day they called me to confirm the date and time for service. I was shocked when the lady who was assisting me when she told me that my service plan warranty ended on the 29 July 2021 and by the time the km did not reach as per contract. What I don't get no communication were sent to me and even on the call that I made on the 11 July 2021 your consultant did not even mentioned that to me and it is not the first time that I am getting poor service from VW.
