I have a Cap One Visa Gold Card with an $800 limit, I got this card after I sent in one of their pre-approved offers. I just received an pre-approved offer for a Platinum Mastercard with a Cl of up to $7500 from Cap One. Is there anyone I can talk to at Cap One to use this offer to get an CL increase to my Gold card or get the MC and roll my Visa into the MC? Mark
