From Saturday to Yesterday at 1910, I had received a total of 20 calls from different companies all trying to sell me a mobile handset on behalf of 3G. Whilst it is obvioulsy a necessity for these people to try and earn a living by selling things you don't want, I felt that the number was becoming intrusive. Having used tact and diplomacy in an attempt to speak to a higher authority at the company involved, I finally decided to contact the company they were selling on behalf of. Unbelievably the young lady on the sub-contintent gave me a website to use to enter details to have your telephone number put on a list to ensure no further calls are received by cold callers. I was sceptical to say the least, and when the URL didn't work, I thought it was a wind up. I then tried via google and used the cached version of the web page. This time I found it and checked the URL. It wasn't on HTTPS: but once I went in to register it was.
Too cut a long story short, Telephone Preference Service is the site that you can register on. It takes 28 days to complete the registration. I assume this is because of the number of different companies involved, but can't wait for 1st November to see if this actually works or not
