Ford Service or lack of

My parents bought a Ford Ranger from Jarvis Ford in Adelaide. They are very happy with the vehicle and after returning from a two month trip through NSW and QLD towing a 18' van, they could not be happier with they way the Ranger went and the fuel usage (400km on 45ltrs average).
Until they got the Ranger serviced at Jarvis Ford.. 20000km service at a cost of $800. That hurt a bit but it was tappets and diff oils so they wore it. When they arrived here at my place I had a look under the Ranger to find that no diff oils had been changed and that the drive shafts had not bee greased. The plugs and grease nipples still had the red dirt from the trip in the flinders Ranges. They had not even checked the transfer case oil level.

Dad rang Jarvis Ford today and spoke with the service tech. He said that he did not realize the diff oils were part of the 20000km service even tho Dad was charged for the oil on the invoice. Also when confronted about greasing the drive shafts he said it was done. Well they sent a Mechanic out (100km) to finish the service, so Dad asked the mechanic that turned up if the drive shafts had been greased and he sheepishly said NO!!. Needless to say Dad was not impressed and will be in touch with Ford tomorrow.

Also just to add they charge $68 for 6ltrs of engine oil. I think its Mobil. Over $10 a ltr is robbery. Nice way to treat you customers after buying a $50000 vehicle
