I do agree with the OP that getting through to Sixt on the phone can be an exercise in frustration. They recently "upgraded" their phone system, and now unless you are calling to make a new reservation they basically just tell you to go to the website, which can be problematic, since their website in many ways sucks. For example, if you make a reservation anywhere other than Sixt.com and want to confirm or change your reservation, good luck with that. You are SOL.
