Rac approved guarage

hI I WENT FOR SERVICE AND MOT TO A RAC APPROVED GUARAGE AT WATFORD, BUT SERVICE WAS REALLY POOR AND CHARGES ARE ALSO EXTRA. I DID NOT GET ANY BENIFIT AS RAC MEMBER ALSO.
BESIDE THAT I HAVE TOLD A PROBLEM AND THAT WAS NOT SOLVED AT ALL AND WHEN I WENT AGAIN THEY ARE NOT READY TO LISTEN AND TOLD ME TO COME NEXT WEEK AS THEY ARE BUSY.
I AM REALLY UPSET HOW COME RAC CAN APPROVE SUCH KIND OF GUARAGE.

NAME OF GUARAGE IS MOTOR SERVICES WATFORD LTD
