Thanks for your reply!
As far as I can see the Financial Ombudsman Service can deal with complaints about the banking sector and I assume this covers personal loans.
Another thing I've checked since my last post is the case fee that firms have to pay if the Ombudsman decides to investigate further. It is now £400 per case. Therefore, if everyone who has received a final 'resolution' letter from Abbey takes their complaint to the Ombudsman it should cost Cahoot/Abbey a lot of money.
The other thing the Ombudsman service does not like is a large proportion of complaints from firms being referred to the Ombudsman service. Historically, Abbey have had high percentages of referrals to the Ombudsman.
Therefore, the more people take their complaint further, the more beneficial it will be to consumers.
I am also going to write to the Financial Services Authority to notify them of this practice. Essentially, Abbey/Cahoot have reeled in customers and then held them to ransom.
Not everyone may be in a position to move loans elsewhere i.e. change of circumstances, number of recent loan applications affecting credit rating and also, what we are currently seeing in the banking sector...a tightening of the issue of credit agreements. The latter point is in the most part, due to the banks mishandling the amount of lending and in this particular case Abbey are effectively charging us to make up for their business mis-management.
