What phone number did you call?
FYI, in general it might just be too early for them to give you a CLI. It's usually good to wait 6+ months for most (with a few exceptions) lenders before asking.
I would suggest trying another number / calling the same number another time. That seems rather unusual to me, but I've never tried it myself.
Sounds like a student product although it's not too restrictive on CLIs (they can grow, just not that much or frequently). Hopefully, you didn't select this one when you applied since I'm not sure they can generally change it once the application is decisioned, but I'm sure stranger things can happen with BOA. How long have you had the card? I would give it a few months if this is a newer account and check back with another analyst to determine PC elegibility. If they confirm the product code as a "student" version, then it's likely to remain so.
