Is it an invoice or was it already charged to a credit or debit card? I would be pissed too but don't pop a vain, it is an obvious mistake and shouldn't take much to correct.
It is frustrating getting hung up on all the time. I went through that for 3 days last year dealing with Intuit's support people in India. Every time I got to a point where that person couldn't think of anything else they put me on hold then I was disconnected
