Responding to figures released by City watchdog the Financial Conduct Authority, (FCA), that show Barclays as the UK's most complained about bank, Ashok Vaswani, Chief Executive of Barclays Retail and Business Banking, said his bank was "striving to do better."
Though complaints were down by 11%, the bank received 370,733 complaints in the first half of 2013. Mr Vaswani said:
Whilst the number of complaints we receive is reducing sustainably as we work hard to put our customers at the heart of everything we do, this is no time for self-congratulation.
Even one unhappy customer is one too many which is why we must always strive to learn lessons on how we can do better.
That is why we will now publish complaints data every three months with additional information on how we are tackling their root causes.
