The employee who told you that is clueless. And I have no idea how adding more than three rasboras would mess with your water parameters.
Get three more rasboras as soon as you can. Add the Cherry Barbs a good two weeks later (and, again, get at least six... they can get aggressive if they're in small numbers).
