I have been getting calls from this number at all times of the day, and sometimes up to 6 times a day! Can't the number be traced and made to stop calling as it is extremely disruptive!

Persistant pests. Call centre that is not fully staffed and when the computer dialer connects and there is no-one from the centre to pick up the next call, it waits and drops out. I have had 5 calls from them in one hour. Should be a law against these guys.
I believe they are part of a conspiracy from a foreign government to weaken our national economy, through lost productivity. 5 calls a day, with each call interrupting the concentration of a worker, even if the call lasts 30 seconds, the worker has to refocus on their task to avoid mistakes and the whole process wastes 5 minutes of productivity x 8 or 10 repetitions a day, across the country, is a massive cost. What, though, of the errors made by staff that don't refocus before continuing their task at hand? These guys should be traced back to point of origin and terminated
