Research from uSwitch.com shows that 20% of customers are not happy with their credit card provider.But despite this, the report – issued a year after the OFT effectively capped credit card charges at £12 – found that consumers are not acting with their feet as they typically stick with the same provider for six years.

Capital One fared worst, with 32% of its customers not satisfied, while Nationwide came up trumps, with a satisfaction rating of 94%.

Mike Naylor, personal financial expert at uSwitch.com, said: “Credit card companies are relying on customer lethargy, and, with over half of consumers never comparing their existing deal with the rest of the market, people are paying directly into their hands.”
