I have been receiving calls on my mobile from these people, for about 3 weeks, at a rate of about 8 every day. Most of the calls are silent, but sometimes the caller asks for me by name and then hangs up. I traced the calls to telegen at Brighton and called to tell them to stop bothering me. The woman who answered said they had been calling me on behalf of Axa Insurance. Making nuisance calls to drum up business seems pretty stupid to me! I have complained to Ofcom.
