I was fortunate enough to be able to speak with a very nice gentleman that was from the US in Virginia and he changed all my rates for me, but it took about 90 minutes to get all of my clients changed.  I called around 4:30 in the afternoon to the phone number under help and contact us.

The phone number it gives me is [removed] and then it gives a case number to reference, but he never asked for it.

Good luck!
