Also had this problem for two weeks now. They use a system called ACS (Automated Calling Systems). The systems dials more numbers than there are staff available to speak to the person who picks up the phone, resulting in a silent call. To explain, for people like Milly, Their phone will ring several numbers at once, the first person to answer will be spoken to and the others will hear silence.
Government has just put up the maximum fine to £2 million for companies causing nuisance and distress with ACS.
Report them to: OFCOM Tel: 0300-123-3333
The more people report the calls, the more chance of a fine being levied.
.... Have you done it yet?
