Query: HQ 55 Not HQ 55 plus as described

This item arrived quickly and seems to work, but it is not HQ 55 plus as described,and there are 3 replacement heads instead of 6. This is really another part number which is at least $6 cheaper. Now it is used and cannot be returned. Amazon should not allow this kind of deception.
