The 1/8 carbide end mills sound handy if you have a way to use them, and a good price also. But considering the small amount of money involved I guess I would take the $3.00 credit and move on with life.
I would leave a review stating your experience. I went through something similar a couple weeks ago. The item did not match the ad spec, but in my case it worked out fine because the item sent actually had better compatibility with what I was doing.
Unless the O1 is hardened, a cobalt bit would be my choice.
EDIT: If it work hardened, then the hardness is very thin. I would recommend a cobalt bit, slow speed, and a lot of pressure. No coolant or cutting oil. It also may be possible to use one of those carbide end mills and plunge to get through the hardened part.
BTW, you should be able to edit a post for a couple of hours.
