I'm so so sorry for your experience! This may be irrelevant as you say you don't have insurance right now, but if you google a forum called verticalsleevetalk, there's a whole section for people who have had similar experiences as you and had to have their band removed - it's called band to sleeve revisions. Just something that couldn't hurt to check out, I think.
As for right now, I don't know if there's anyone with a band here (sorry if I'm wrong!), but there is a sister site to verticalsleevetalk called lapbandtalk that I'm sure you could find someone with the similar issues there if not on verticalsleevetalk. I really hope someone somewhere (even here on 3FC) can help you out and wish you the best of luck!
