Photoshop: Images not saving at right size and resolution

I resize an image in Photoshop CC, and save it at a particular size and resolution. When I reopen it, it is at a different size and resolution. Adobe were unable to resolve the problem, advised that I needed a new root account, and referred me to Apple (I use an iMac). Apple were excellent with their attempts to resolve it, and provided a new account. The problem still exists, and as I have to resize images in considerable numbers, it is really difficult, having to resize them every time they are opened. Photoshop will not save images at the correct dimensions, and the best Adobe could do to 'help', was to refer me here. I would be grateful for any help.

Hi everyone. There are several different issues in this thread. 
From what I can see there are errors in using and understanding resolution vs. pixel size but there’s also something else I encountered as well.

That is: Sometimes saving JPGs, the specified DPI value will be dropped. So when opening a picture saved as JPG from photoshop, photoshop assumes that it is set to 300 DPI. Thus the dimensions (in metrical units) may change. Although the pixel size of course stays the same. I have not been able to resolve that issue, nor to say whether it happens always or only on certain occasions.
