So I've had Cap1 for 6-7 years, starting with the Platinum card in the step-up program during my rebuild. I forget how long the program was established for( I believe it took 6 months to build up), however, I ended up capping out $750 with an understanding that would be the max for that particular card, which was by far the lowest limit card I had.
I also received the QS Cap1 card a couple of months later that started at $3000, which is what it still is today. Several months ago, I applied for a cli on the QS card, "denied"!! I called in and told them how frustrated I was since I've had the card for 6-7 years, never missed a payment, and regularly pushed usage to the card. Someone called me back from C\S and left a message but never called back.
Fast forward to today -- I receive a congrats email from Cap1 stating they've increased the limit on my Platinum card to $3250 from $750. Very strange but I'll take it! Thanks community!
