I hope you feel better soon, It could be the machine still had chemicals in it from cleaning, I cant beleive they wont do something for you, thats bs. I would be calling the owner and having the cops there, hugs and please keep us updated. the reason i say that is i got tea from a resteraunt before and got very sick, it taste just like what your tasting, i went back to complain and found out the machine was never cleaned properly and still had chemicals in it
