Z3C Screen broken. How long does the repair take (Germany)?

Hi,

yesterday, I pulled my Z3C out of the pocket, and the screen was completely shattered (it didn't fall down, no hard impact, nothing - just had it in my pocket - as every day). Everything still works except for the touchscreen.

I've already contacted the Xperia Customer Service in Germany, and they said they can fix it for 150€.

My question is: how long will it take until I get my phone back? Does anyone have experience with sending in their phone? Prefereably in Germany?

Thanks
