As cartridge bearings wear and develop play, the entire cartridge unit is replaced. Cartridge hub service is not covered in this article." This is why they said replacements aren't available.
Think you need to find a new LBS, as the info they are giving you is bad.
For the hub, all 11 speed hubs are backwards compatible (to 8/9/10), just use a 1.85mm spacer (available from any good LBS)
If your hubs are cartridge bearings, not cup and cone, then as described in my post above, you just press/hit the old ones out, and replace (press in) new ones of the same spec. The info that they can not be user serviced is correct, as in they are replaced as a complete unit, but bikes use industry standard bearing, all you need to do is find the part number (will be like 6001 2RS) and have a new one pushed in; no further adjustment needed.
