I had the same experience. I called last week to request a CLI and was told 7 months also. I opened the card in November and use it all the time, but the CL is only 1k. I put at least $600 on a month and was hoping for a little love since every time I go in, I use such a high percentage of the available credit and have to make a payment. Oh well, I'll give them a call back in three months.
Current:
TU (5/14/14): 796 (Inquiries; 8/23/13)
EQ (3/23/14): 791 (Inquiries: 8/23/13)
EX (9/24/13): 780 (Inquiries: 7/2/12; 11/20/12; 7/30/13; 8/23/13)
Goals: No new inquiries for 2014, 800 for all CRs by 12/31/14
