Clearly, this number is a nuisance that shows up repeatedly on both landlines and mobiles, often at odd hours. Callers rarely identify themselves, use broken German with foreign accents, and sometimes claim to conduct surveys or sell products. The pattern matches classic spam or telemarketing behavior: high frequency, no voicemail, and immediate hang‑ups. Protect your device by enabling built‑in spam alerts, adding the number to your block list, and refusing to engage with unknown callers. If a call seems legitimate, verify the organization through an official channel before sharing any personal data. Staying vigilant and using call‑blocking tools will reduce unwanted interruptions.
Keine Ahnung, wer das ist. Keine Nachricht auf dem AB. Ich sperre die Nummer. Ich bin es leid
Es handelte sich um eine Marktforschung.

Be cautious, this number uses a blocked caller ID to conduct surveys and then blocks you
Following three consecutive nights of late evening calls, the harassment shifted to a different number, with the last one being the third instance, exhibiting identical behavior, including early morning calls on weekends.
Receiving calls on a non-public number raises serious concerns about the legality of such actions, prompting me to blacklist and block the number.

Daily calls are being made at an alarming rate
Unknown number doing a survey on local politics. Quick and painless, I guess.
They are terrible, trying to verify our datas, thats just a scam, I blocked the number and now I have peace
This behaves very unseriös, when you anser the call, your own number is displayed instead of the actual number, isnt this ilegal?
Harassment calls from unknown number. Keeps ringing, no message. Annoying as hell.
