    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.

    1. Pete Wise reported Boots appliances with the number 01616966054 as Harassment calls

      Its not just AO
      I just received a call from a young woman claiming to be from boots appliances, in the pretence of confirming delivery details etc. In fact her sole purpose was to sell insurance cover!
      She repeated every detail of my delivery, which I already know, told me they can remove my old appliance, which I already know etc etc etc then asked me why my old appliance was broken! All leading to the insurance pitch! These are badly scripted insurance sales calls!
      I am very disappointed that boots have potentially 'sold' my details to a 3rd party and that they allow this.
      I have never experienced this from currys etc,
      Very dissapointed!
