Right when I started using Enterprise bec of the Chabad account for some reason i got enrolled in it, It helps cut lines there is a special line for you, and they have all been really nice to me, I dunno if its bec of the Plus or bec ive been using a business account.
And yes it will work with the Corporate, just sign up for it online, and in ur profile put the Chabad account there, therefore you dont have to remember the numbers again, in ur profile it is written that you work for Chabad. Thats the way ive had it for the past couple years!!
