The UK Financial Services Authority found that complaints about mis-sold payment protection insurance (PPI) increased 85% in the last six months of 2011, totaling over 1 million claims. Major UK banks were overwhelmed by customers demanding compensation for improper PPI sales. PPI was insurance sold with loans and credit cards, but many customers were mis-sold policies when PPI was unnecessary, unrequired, or sold without consent. The spike in PPI complaints has increased claims against banks by 21% compared to the last half of 2011.
