I will endeavour to find out Andy through the limited ammount of statements I have. Im not holding my breath re the full breakdown, but as ims says how can I be expected to accept an offer when I have no idea how the interest has been calculated? Would the FOS take a dim view on how RBS are dealing with my request re the breakdown? Surely there must be some guidelines to be adhered to.

Totally agree ims21! I would accept the offer straight away if I was 100% sure that it was a fair. They just seem unwilling to show me that it is a fair offer! Do you think I should still put it in writing to them?

The interest rate on the card was 1.456% per month which I believe equates to 18.9% APR. Just phoned again and spoke to a young lady who refused to give me her surname (against banking policy apparently) to ask for a full and itemised breakdown of the offer. Initially she said that they only calculated interest using FOS rate of 8%. I told her that in my offer there was an ammount attributed to compound interest at rate charged on the card and I need to know how this figure had been calculated. She said she would email the relevant department to ask for my breakdown as requested, but she didnt know if they would do it or not! Now its a case of waiting for yet another 7 to 10 working days to see if anything arrives.

Ok thanks. I'll let you know how I get on.

Does this have to be done in writing or can I ask again over the phone? Once gain thanks for your help.

Hi, thanks for the rapid response, No unfortunately I dont have all statements. During my first phone call with them I asked for a detailed breakdown of the offer and 10 days later received a letter only showing dates and ammounts of PPI paid. These are what I used to calculate compound interest on the FOSCISheet v101 from 13/12/03 to 21/04/13 which is when I made my complaint.

Hi all, this is my first post and may be a bit long winded so please bear with me. I complained to RBS about PPI on the 21/04/13 on a Mint c/c that I took out in Dec 2003 and 8 wks later received a reply along these lines, You will be pleased to know I have finished my review into your concerns about your PPI. Your concerns are important to us. In the circumstances, as a goodwill gesture and without admission of liability the bank is prepared to make you the offer set out below. To cut a long story short they go on to offer me £888.62 broken down as follows... Refund of premiums paid between 13 Dec 03 and 13 Jan 09 £532.43 Compound interest on premiums based on unterest rate charged on c/c £93.61 Total £626.04 Gross interest @ FOS rate £328.23 Less tax at 20% £65.65 Net interest £262.58 Total offer £888.62. Now, I have only just paid off an outstanding balance of £105 which has been there since Jan 2009 (messy reasons, business going belly up, divorce etc) but not sure this is relevant! On receiving this offer I phoned RBS and asked for a breakdown as it was a bit confusing how they had calculated it and this week I received said breakdown which showed nothing but the premiums id paid each month, so after searching this site for relevant calculators I did my own calculation. Using the FOSCISheet v101 for the compound interest, at 18.9% APR it calculated it at £1757.88, lots more than the £93.61 RBS have offered. So today I phoned them again to point this out to them and a young lady told me I had 2 options if I didnt agree with their offer. 1/ Provide proof that I had paid more interest than they had offered, or 2/ Take it to the FSO. I asked how I could prove it and she told me to provide bank statements which would show the ammount of interest paid!!! When I pointed out that bank statements would only show the single ammount paid off against the card and wouldnt show interest, she just said take it to the FSO!!! Now my question is do I accept the offer of £888.62 or do I take it to the FSO based on the FSO spreadsheet calculation being so much higher than RBS offer? Any help and advice would be appreciated and again I apologise for the long post. Claygo
