Yes some of them are trying to make a living but . . .
I had a call the other day from someone from an accident claims firm who said that they had been given my number due to an accident I'd had. That is phishing pure and simple. They are making things up in the hope that they really will connect with someone who has had an accident.
Or the calls claiming to be from Microsoft and that they are aware that I have a virus on my computer. This is a scam pure and simple and dishonest. These are people trying to earn a living by dishonesty.
My number is registered with the Telephone Preference Service.
As their website says:
The Telephone Preference Service (TPS) is a free service. It is the official central opt out register on which you can record your preference not to receive unsolicited sales or marketing calls. It is a legal requirement that all organisations (including charities, voluntary organisations and political parties) do not make such calls to numbers registered on the TPS unless they have your consent to do so.
Organisations with which you have an ongoing relationship, for example those who regard you as a customer, (or in the case of charities - a donor) may well gather your consent during the early stages of your relationship with them and will therefore be entitled to call you even if your number is registered on TPS, unless you have previously told them specifically that you object to them calling you for marketing purposes.
The TPS can accept the registration of mobile telephone numbers, however it is important to note that this will prevent the receipt of marketing voice calls but not SMS (text) messages. If you wish to stop receiving SMS marketing messages, please send an 'opt-out' request to the company involved.
As TPS registration only prevents marketing calls, organisations will still be able to call you for the purposes of genuine market research.
Yes people are entitled to make a living, but by the same token, I am entitled to privacy and freedom from unsolicited calls.
