FOS reveals it isn't just PPI problems driving up claims complaints about catalogue accounts expected to see 25pc increase this year.
The Financial Ombudsman Service (FOS) has seen a 30pc increase in claims in the financial year.
This has largely been driven by the huge volume of people complaining about mis-sold payment protection insurance. In the last quarter the Ombudsman received 145,000 complaints about this insurance, which was sold by banks alongside loans and credit cards. This takes the total for the financial year past to almost a quarter of a million complaints.
But the FOS said that with economic conditions worsening, it had also noted a significant rise in consumer credit complaints.
Many customers are now finding established lines of credit closed off to them are seeking alternative forms of finances away from the high street banks.
As a result the FOS has seen a marked increased complaints about catalogue shopping accounts. The FOS said this is the third most complained about consumer-credit product (after point-of-sale loans and hire purchase agreement). The FOS said it was currently receiving up to 30 complaints a week on this issue. If this continues complaints about catalogue account will be 25pc higher than the previous year.
A spokesman said: "Many of the complaints we see have come about because the way consumers operate their catalogue accounts can be complex. Problems can arise, where different payment arrangement apply to different items.
"Or where consumers missed a payment and went into arrears, often because they hadn't realised their payment date was on a 28-day cycle rather than being on a fixed date each month."
He said they also saw a number of complaints about the quality of items bought from catalogues, and adverse information being recorded on a customers' credit file.
Many complaints also concern returned items, if these are returned late or have disappeared in the post.
Most complaints were resolved via mediation, without the recourse for a full Ombudsman's judgment.
In total the Ombudsman received 180,679 complaints between October and December 2012. It said the number of complaints it received in this quarter was more than it received a year for the period 2000 to 2010.
The FOS said it has received almost a quarter of a million complaints about PPI this financial year out of 341,666 complaints in total. .
So far in this financial year the Ombudsman has ruled in the customers' favour I around 47pc of cases, but this rises to 62pc for PPI complaints.
