It sounds like you had to opt-out of arbitration, which is a gotcha.

It's crazy to me that contracts are permitted to circumvent the laws of the land.

_proud opt-out'er right here_ lol

the catch is that there's no proof, they don't acknowledge it. i sent a paper letter and email.

If you sent it with something like gmail you should have acceptable proof right? Unless you deleted it from sent. Or can that be spoofed with a different date with an outside client or something?
