Customer no priority

No service when booking online on 18/12/2017. Had to phone and confirm. Service wasn’t booked. Took in vehicle 7h40 on 3/1/2018. Only received call with quote at 13h51. Service completed at 15h50. Labour R3314-20? Car is making the same noise as before service.

Phoned today to complain. Hold for 5 min with no answer. Not the first time this happened. Previous bad experience as well.

I own 2 mercs - maybe time to change my beloved brand!
