Ministers urged to act as nuisance call complaints treble in two years Claire Milne, visiting senior fellow, claimed complaints to Ofcom hit 3,901 in April, compared with 980 in April 2011. The Telephone Preference Service (TPS) received 9,849 complaints in April, up from 2,989 in the same month two years ago. The elderly and disabled suffer more as they are likely to stay at home during the day. She added the "burden of proof" for enforcers should be reduced, a single online complaints mechanism should be introduced and all commercial calls should be identifiable. She said: "The enforncement rules seem to have been designed to gently guide errant businesses back to better behaviour, rather than to reduce problems for consumers." Which? last week urged Culture Minister Ed Vaizey to act, claiming his dithering over the past month meant UK consumers had suffered another 767 million unwanted calls. The very next day, Government sources claimed ministers would soon propose changes to the law to lower the threshold of what is considered a nuisance call. Last month the Daily Telegraph revealed that new Ofcom rules later this autumn could slash spammers' cost of making cold calls by as much as 83 per cent.
