The Citizens Advice Bureau wants cold calls about the mis-selling of Payment Protection Insurance (PPI) to be banned and said it is "completely unacceptable" for calls to disrupt family time and work meetings.
Over a third of the complaints Citizens Advice handles about financial services stem from a cold call.
There is a particular problem with claims management companies. People are finding that sometimes the promises made over an unexpected phone call aren't delivered.
This means people who have been mis-sold PPI lose out twice: first at the hands of the bank and secondly from the claims firms because they don't get the full compensation they deserve. I want financial services firms to be banned from cold calling.
