Twice in 3 days, each time during a meal, I've been called by this number. When I pick up the phone no-one answers me. I replace the handset, wait 10 secs & try to dial 1471 but the line is still open. After about 30 seconds I can get a dialling tone again. The Telephone Preference Service needs new legislation (or something) as my life is interrupted most days by nuisance calls.
