There is a clear misunderstanding here. If you spent money (made a withdrawal) from an HSA (health savings account), the administrator MUST issue a 1099-SA. I doubt that any legitimate bank would refuse to provide one.
If you have an HSA and made withdrawals, call again or check your account on their web site. You may be able to download the 1099-SA. You do not get a 1099-SA if you only made contributions and no withdrawals.
If you have an FSA (flexible spending account, from a work cafeteria plan), then you don't get a 1099-SA and don't report it on your return. An FSA is not the same as an HSA.
