How do you reach a Customer Service Representative that is stateside? Every rep I talked to today doesn't seem to understand my situation. This is so Frustrating!!

I renewed my yearly subscription & pd for it, 2 weeks later QB charged my credit credit and shouldn't have, then they credited my card for an amount that was more than the charge and changed me from yearly to monthly. I need to speak to someone in the US that understands this mess. Spent 4 hours on the phone this morning and accomplished nothing.
