Makhita ripping me off

My makhita drilling machine needed a set of brushes, The machine WAS WORKING. I decided to drop it off at the agents for them to change the brushes. They were to quote before replacing the brushes. I also asked them to look at the selector switch as it worked perfectly BUT didnt 'clip' 100% into place. We had been using it like this successfully for YEARS. I also asked them to also quote for 'a service'.<br> I got a quote back (8 days after booking it in) which included changing of armature, field coils, grease vessel, spur gear, baffle plate (Why are all these needed - the machine WAS WORKING), brushes (which is what it went in for). When I phoned Makhita today all I get told is that 'that is what is needed, I must come look'. I HAVE NO idea that I would even be looking at my parts??<br> I then ask to speak to the manager ('Hes' JUST stepped out'). I try his cell phone, no answer. <br> I re-itterate. The machine WAS WORKING. It needed brushes, I also wanted it 2 b serviced.<br> I am a qualified practicing electrician of 29 years. I have an elactracl and electronic diploma and have taught electrial up to NTC 6 level. I DO believe that I know what I am talking about.
