Latest from our blog

    We've all had to deal with the same thing. Your phone rattles furiously as it's bombarded with nuisance call after nuisance call and you have no way of knowing who's calling. Will it be over enthused telemarketers or, perhaps even more annoying, a swift click and the dialing-tone drone? Should you take the call or ignore it? Who's on the other end?
    Rest assured that you're not alone. In a world where cold callers can sometimes seem to hold a global monopoly over phone lines, tellows aims to provide a solution. We function as a vast online database of phone number profiles, generated thanks to feedback and reviews from our online community. Providing an online platform where users can share their experiences of these kinds of calls and flag up numbers responsible for junk calls means that information on suspicious numbers becomes readily available, helping other members of the tellows community to anticipate potential risk calls.

    1. Adesso basta. reported enel energia with the number 00393231440223 as Aggressive advertising

      Ricevuta chiamata alle 4,57 di notte. Voce registrata enel energia per cambiare gestore. Mi ha preso un colpo. Ovviamente mi sono svegliato perché ho genitore anziano e devo essere sempre raggiungibile. La stessa chiamata l'avevo ricevuta la mattina. Pare che il 17 giugno abbiano chiamato anche di notte. Follia. Da denuncia. Bloccate il numero.

      Six calls in three days!
      I agreed to self isolate for the required time and I am not a liar. Have followed the rules for 20 months. The area I legally visited has about 100 cases and should be on the green list. I was safer there than I am in the UK after the Government let all the Indians come
