Yesterday I ordered a copy of Vista Ultimate OEM from Tekheads. The item arrived earlier today but they had sent me Home Basic instead. The problem is, I've broken the OEM seal on the packaging, and it was only after breaking this seal that I had any way of knowing what was inside. There is absolutely nothing on the outer cardboard sleeve which indicates what version of the software is inside. I have submitted an RMA request on their website but I've got a feeling that they're going to be funny about accepting a return seeing as the seal is broken. Has anyone been in a similar situation before? Am I likely to be screwed over by this? Would Microsoft be likely to help out if I were to contact them regarding the matter?
