I took a quote from this company, I was told on the waiting phone to state that I do not want to have other companies bothering me with spam or unwanted phone calls. I asked the lady who sounded Asian I would like not to have my details forwarded to these companies. She replied if your not having an insurance from us you have no say in the matter (it was words to that effect). I was outraged and I wouldn't have insurance now if they were cheaper. I am now blasted on the telephone by companies selling even though I have telephone preference service set up! This system of having to opt out is an outrage! I want to spit feathers at this unwanted intrusion and I am damn rude to those who call. I am in chronic pain and to get to the phone when I am in the garden and can hardly move is an enormous effort. I have to answer the phone because my wife looks after my mother-in-law and I have doctors and hospital ringing me. This unwanted intrusion HAS TO STOP. The world we live in has no respect for our privacy.
