Air carrier Inspector reported inspections on holes on the B787 cargo door hinge brackets are not being accomplished and being signed off as complete by an outside vendor.

Narrative

SAAB released a bulletin to do a hole check on the 787 cargo door hinge brackets. An outside vendor has been doing the inspections. Twice I've found that the vendor's employees have been pencil whipping the hole inspections in order to not have to complete rework and slow down the delivery schedule. I noted the work order with a description of my inspection rejection. It illustrates that only 1 of the required 5 fasteners have been removed. The one replaced fastener was installed without required sealant. The 1 fastener also has FOD under the head and protruding out. It also illustrates there are different size heads of the 5 fasteners that are supposed to be the same part number. It also shows that there are different size washers installed that are supposed to be the same part number. Since my rejection; the rejection was ignored and signed off by another inspector. Completely signed off and forgotten about. The unsafe condition still exist. I've made inspection management aware. It's being ignored. I've made several reports. Every time; issues get swept under the rug.
