Sesame retains the top spot in the ranking, with 100 complaints between 1 January and 30 June 2017, but reported slightly less than the 104 complaints it faced in the previous half.

SJP reported 58 complaints in the second half of last year, which has now risen to 72.
The SJP group of companies chose not to publish its complaints data for the second half of 2016 on its own website because FCA rules say this must only take place if 500 complaints are received to the firm, regardless of whether they go before the FOS.
Openwork saw a fall in complaints from 70 to 61.
Hargreaves Lansdown Asset Management came in fourth place with 50 complaints.
Openwork had the highest uphold rate of the group at 47 per cent, compared to around 19 per cent for the other three firms.
