I think you opened up too many GE accounts too soon. They were probably concerned of potential identity theft. You most likely set off a fraud alert in their system. Most store cards are backed by GE these days. I think I opened a total of 4 GE accounts but I spaced my apps apart. I opened one in May then three months later I opened a second again. And the last two a month later.
I say to pick the two cards you'd feel would be most beneficial to you and call and request to have the accounts reinstated. They will probably ask you why you app'd for so many store card. Be honest about it.
There is your answer OP. Any status on if they reopened them?
