Issue with MAC concealer?

I went to my local MAC counter and was matched with NC25 for my under eyes. She gave me the pro-longwear concealer. I had originally wanted the studio finish, but she just couldn't be bothered. My foundation shade is 150 Buff in Revlon ColorStay foundation. NC25 is WAY darker than my foundation shade, and way to yellow, too. I have moderately dark circles (student) and very oily skin. I do have an issue with concealer creasing under my eyes. I am going to return the concealer and ask to be rematched. I need a concealer that is long-lasting, offers good coverage, and will not crease on me. Select cover up? Studio Finish? I know I probably need an NC as the pink tones will help correct my bluish circles. I have fairly neutral skin undertones. Definitely not strong yellow, and definitely not strong pink undertones.
