Call the backdoor number and ask if they need more information or if there is anything else that they need. Sometimes they need to verify your information.
Stop back and let us know how it goes.
How long does it usually take for the WalMart card to do credit line increases? I'm planning on using mine sparingly and just making small purchases and paying them off fully every couple of months. Just asking.
You should ask for a CLI from Walmart after every 4 statements if you don't get one automatically.
