No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
In my experience with equifax it is sometimes best to forward them copies of your statements and a copy of your driver license and SS card with a letter detailing the non reporting. They seem to respond to actual paper more efficiently then by phone or online. Old school snail mail....
If your creditor has a credit reporting agreement with the CRAs, and their reporting is not being posted by a CRA, I would send a copy of your recent credit report to the creditor, advising them that their reporting is not being posted by the CRA.
The creditor has a vested interest in the CRA abiding by their credit reporting agreement, and may contact the CRA to get it corrrected.
