Magic number is four months for CLIs (In my experience). Mark it on a calendar and call four months from now and ask for the $35k and see what/if they counter for. Always a SP with Synchrony so you have nothing to lose, but definitely CALL every time.
did you try credit solutions with Synchrony bank (877) 379-8173, give them a try. I was turned down online with my cards but tried the number and was never turned down.
