Phoenix Life attracted more than 400 complaints in the final six months of last year, according to latest data from the Financial Ombudsman Service (FOS).
The annuity provider and closed life fund consolidator totalled 407 complaints, 322 of which fell into the life and pensions and decumulation category.
Elsewhere, more than 200 people complained to the FOS about the Sesame network. Data for the period from July to December 2013 showed the network, part of the Friends Provident group, accrued 213 complaints.
The big insurance groups featured highly on the list with Axa, (603), Prudential (393 cases), Legal & General (386 cases), LV= (353 cases), Aviva (340 cases) and Royal London (305 cases) all garnering hundreds of complaints in a record year for the FOS.
Banking giant Lloyds topped the list over all.
Figures published today show that the ombudsman took on a record 575,836 new cases in total in 2013 – this was an increase of over a third (38%) on the previous year (2012).
Payment protection insurance (PPI) claims made up around three-quarters (76%) – with a total of 190,356 new PPI complaints. Five financial services groups accounted for nearly seven out of ten (68%) new PPI cases.
Tony Boorman, chief ombudsman, said: “The extraordinary volumes of financial complaints we saw in 2013 now looks as if they’re starting to level off at last – and that has to be welcome news for everyone.
“But we’re still a long way from being able to say that PPI is sorted once and for all. Over 1,000 people every day are still asking us to sort out PPI problems that they’ve not been able to resolve directly with their bank."
Boorman (pictured) added: "So with the numbers of new cases still depressingly high, we’re going to need to continue to rely on the patience of consumers and the cooperation of businesses to get us through the substantial workload.
“Away from PPI, there are further signs of improvement, with fewer cases suggesting good news. But in far too many cases uphold rates remain stubbornly high, highlighting the need for financial businesses to do more to demonstrate their longer-term commitment to listen to customer’s concerns as they seek to rebuild trust.”
