One of the worst services I ever got. After paying IBSN, they just disappeared. Really just disappeared. I called on all the number mentioned on website but no response. My taxes were not filled so I had to go to another company and do all that. So I paid 311.27$, got no service and guys just disappeared. Wow, way to go IBSN.
I highly recommend to everyone: "DO NOT use these guys if you are serious about your taxes."
Oh BTW, regarding escalation, I think that's the new WORD IBSN people just learned. So when you will talk to them, they will use it alot. What it means in IBSN world is, NOTHING. So yeah, you can try that and it won't do any good.

Bottom line: IBSN lost one customer at least(that's me) and I am sure this number will grow. Not because I have some personal issues with them, but for the reason that I don't want other people to be treated like I was.
