we are a business and this number called quite a few times to say they are coming to visit our business the next day as some kind of hairschool without even asking if it would be okay, i had to tell her we were very booked and did not have time to show anyone around; caller id also says "ah svcs"

Recieved 2 calls from this number, both from relatives using internet telephony in Germany. Apparently, this is the local number for IPTelephone calls from some German company in this area.

I don't know who this number belongs to when I call it back it is always busy.
