Bad service at Consolidated Auto Boksburg

Took my 4x4 for 80 000km service. asked to replace Diff plug and washer, when i collected the car, work wasn't done got proof, took photos. Service adviser said the mechanic did check???? Took for 90 000km service, gave them a clean car, R11000.00 later, car stayed overnight, collected my vehicle that was under shade netting with storm previous night, service adviser said there was a Que of 30 min, welcome to bring my car back so that they could wash it????? service BOOK NOT STAMPED? Loads of attitude at Ford Consolidated Auto........ Customer service, there is none, would not recommend to take vehicle there.
