Wrong spares supp**** and installed

Vehicle went in for 75 000 kms service(3 weeks ago).The brake master had a leak. Vehicle went in on 31 March 2015 to have the brake master replace.When I collected the vehicle on the 2 April 2015 I found the clutch master was replaced instead of the brake master.Service manager Abie Smith said he would call the same day and let me know when spares will be in - still waiting and driving a vehicle with a leaking brake master...very poor service from the branch. I also complained previously of the poor service with the call center agent.
