Claimed to be from British Gas. Seemed unconcerned when I pointed out that they would be in direct contravention of the new Data protection laws. He was very concerned to get me to conform my post code. A previous call using the same "script" wanted my age as well.
Friendly sounding Asian guy called (on a Bank holiday) quoted my name and asked me to confirm my post code, Which he quoted, So I hung-up. Don't know if a scammer or telemarketing but an unwanted call. (I'm registered with TPS).
