You just have to LUV GE Capital! And the backdoor numbers found here on this sight or at lease I do! 
I Hit the Luv button on my Walmart Discover 3 time in the last two weeks but didn't get any Luv back 
So I decided to call the number on the back of the card. Guess what no Luv there either just a message saying a letter will be sent to you within 7 to 10 business days 
Today I got the dread it letter. And it said, We are not able to assign the credit line you requested because it exceeds the amount of increase our policy allows.
Your credit line as of the date of this letter is $10500
So I called the backdoor number and found the LuV! CLI $3500 now the CL is at $14,000 Yippee!!!!!
CL $408,200
thanks!
