Hello... I've been trying to purchase a new GO from the TomTom online store... every time I click to pay I receive an "An unknown error has occurred. Please check your information and try again." message... everything is filled out complete... tried from 2 different PC's/ 2 different browsers with same results... Is the site broken? Any phone number to reach a live person in the store? ... Have a discount as they "obsoleted" my old XL, but need to purchase thru my account... Thanks!
