Expertadvies
Het nummer +31 534 864 704 wordt vrijwel overal gelabeld als een oproep van I&O Research, een marktonderzoeksbureau dat vaak opinieonderzoek doet. Veel beldeuren melden dat ze ondanks het bel‑me‑niet‑register alsnog worden gebeld. Als je dit soort ongevraagde calls wilt stoppen, blokkeren via je telefoon of router is een eerste stap, maar meld de nummers ook bij het onderzoekfilter en bij je provider. Hang direct op zodra je vragen over persoonsgegevens krijgt en deel geen data zonder verificatie. Een korte, duidelijke ‘Nee, bedankt’ is vaak voldoende om verdere pogingen te ontmoedigen.

Telemarketer, ik vond het zeer irritant.
