Can't get correct replacement part from support

I think it's much more than a warehouse problem. The RMA printout that I received along with the wrong power supply had the part # as RNRPPSU1-10000S. If you google this, you get lots of results saying it's a power supply for a ReadyNAS 3100. However, the images that come up in searches for RNRPPSU1-10000S are NOT of a ReadyNAS 3100 power supply, but rather they are pictures of the same incorrect power supply I was sent--which I believe, after some investigating, is actually for a ReadyNAS 1100. (It looks nothing like the 3100 power supply.) *I* had to give *Netgear* the part number for their own part before they would do anything to resolve the mess. This meant I had to pull a still-functioning power supply (it was being replaced because the logs showed intermittent failure) from a live production NAS with critical data on it, in order to give Netgear a part number for their own part that they couldn't manage to find themselves. (The right part # is PWS-451-1R.) And after providing them the part # yesterday, at the end of the day today I STILL DON'T KNOW IF IT'S SHIPPED YET. This isn't the kind of support that goes along with "enterprise-class" hardware.
