SERVICE

I brought my car in for service in November I mentioned to the Lady that the bonnet has a problem and that the guys should look at it. after the service which took 2 days I fetched my car and when I went to the garage I noticed that the bonnet had not been fixed. I called and was promised a call back after several calls I was told that the part has arrived coz my argument was how do I know if the car was serviced properly if they cant hold and keep the bonnet opened? I got a call that they part arrived (so I assume that the reason why I was not called back was because they were trying to book the part) so I made a booking for the 3rd DEC I had to go away so I did not come, made another booking for 29/12/2015. and today I am told that the part must still be booked its in FRANCE so I must wait another 21 working days and no one want to accepts liability because the lady who was dealing with my car had resigned. I am upset that since November when I took my car in i had to wait and i HAD REPORTED the matter before hand. i am disgusted by the amount of service and the management has not intervened I should just accept this ..its WRONG
