The Financial Conduct Authority has launched new adverts featuring the animatronic head of Arnold Schwarzenegger.
The adverts will be on television, radio, social media and on billboards, while they are 1990s and 2000s themed.
Andrew Bailey, chief executive of the FCA, said: “We know that PPI was sold on a huge variety of credit products throughout the 1990s and 2000s, but many people just don’t realise they had it.
“Since we launched our campaign the largest firms have told us that the proportion of people complaining to them directly has increased.
“This may in part be due to the improvements we asked firms to make to their complaint handling processes, including the introduction of online checking and complaining tools. This means that more customers get to keep more of the redress that they are due.
“We want people to act before the deadline. Dig out that old paperwork, visit our website or call our helpline to find out how to check if you had PPI and how to decide whether to complain.”
Since the campaign launched on 29 August 2017 the FCA has received nearly 17,000 calls to its helpline and nearly 900,000 people have visited its campaign website.
