Over the last few months we have been bothered with a number of nuisance calls, Ofcom call these calls ‘Silent Call’ where the phone rings and when you answer they is nobody on the other end. In some cases the caller has left his number and on other occasions the caller has withheld the number.
On a few occasions I have actually managed to speak with someone, one was doing a survey and were based in inner London (I recognised the STD Code). The gentleman of foreign decent (judging from the accent) was polite enough but very persistent and when I indicated that I didn’t want to participate in survey continue to talk to me about how important this survey was and if I would listen for while, about this time I hung up.
A few hours later the same organisation called again, I listened to is opening statement and then politely said ‘No Thanks’ and hung up. Now this kept going on for a few weeks, on Friday I finally lost patience and told the operator that under no circumstances did I wish to be contacted again, but he kept on and on, finally at the end of my tether I once hung up and switched off the phone. After a few hours I switched the phone back on, within 15 minutes it was the same company again, I said that you phoned me not long and I was interested in doing your survey, the guy on the line had the cheek to say but I haven’t phoned you, I pointed that he maybe hadn’t but your company had, I told him that I would be reporting him and his company to Ofcom and hung up.
Now I have been on the Ofcom site and reported them, but they do not investigate calls like this only monitor them. So how do I sort these people out is there a procedure, police or something I go through? To tell you the truth how I actually never swore at the guy I never know but I do want something done. Any suggestions?

There is some legislation called the protection from harrassment Act, but it seems to leave it to the individual to intitiate the protection mechanism it provides. OK if you are on legal aid, but pretty useless for the rest of us.
I have however found that people in call centres don't know this, and it can be used to get them to stop if you ask them to confirm that they are recording the conversation for 'training purposes' before quoting it at them and giving them notice that you will consider a second call will constitute a breach of the Act.
