Look up through my posts... exact same thing happened to me. But I later came across the cingular.com/discounts link, which when followed and filled out, resulted in me getting a different email than the two I got for the verification to get the discount. THAT email had a link to the premier site. No login info, it just goes straight there, and automatically recognizes my company.
And as I mentioned, the discount I got earlier in the week disappeared yesterday in OLAM. Today, it has re-appeared (with no additional action by me).
