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. Join the international community that is currently operating in 47 countries with more than 200,000 users on a daily basis and download the new tellows app today for your iPhone or android.

    1. US traveller reported Government tracing covid with the number 03001232008 as trustworthy number

      It is Covid tracing, as others have reported. In my case they are being slightly psycho about it, having called me on Wednesday, Thursday, Friday & Sunday so far. (Why not Saturday? I don't know why not Saturday.) Each time I am required to respond to the same script. It is now Monday morning & I'm waiting for Call Number Five.

    3. Christine reported You Garden with the number 08446569569 as Cost trap

      They provide poor service and never update you about delays with your order, so you try emailing and get nowhere then have to call. I have just been informed by my service provider by way of my latest bill the cost for this call, and at no time did I know it was a premium rate or that I would be scammed into this extra cost for their poor service. I wonder if it is deliberate to add to the company profits. This is the last time I will order from this company. They are the suppliers for the Daily Mail garden shop also.

    4. SCAM INDIANS has been reported with number 01218178828 as Aggressive advertising

      SCAM - just answer the call and abuse them back, so satisfying. Waste their time as they waste ours
