black horse wrong info on credit file

jacey45

I had a mortgage certificate from the Abbey in May 2008 for a house I was buying. My husband and I had been customers for over 15yrs and never been late with a payment.
I was buying the house with a third deposit and thought everything was fine until the offer was finally refused and the reason they had given was because of missed payments on a loan and the fact I had not given them all the information needed regarding loans I had outstanding.
I was totally shocked. When I approached Experian it turns out that the Black horse had said that there was missed payment on a £50k loan.
The reason for the missed payments was because my husband had died suddenly and his account had been closed and everything went to probate. As soon as I could everything was put into my name and any missing payments were cleared.
When I sold my house the £47k was paid off in March 2007 in full.
When I rang the Black horse that they had not cleared my credit report they apologised and said it would be done. I pointed out that because of their negligence I had lost a fixed rate mortgage of 5.4% for 5yrs and ended up going with Birmingham Midshires with a fixed for 2yr deal of 6.4%.
I thought that everything was sorted out and it was not until I tried to apply for a 0%intrest credit card that I learned Black horse had not rectified my report.
I have phoned and wrote on many occasions because I am really angry that they could be so cavalier in thier attitude.
I have now written asking for some sort of financial compensation but they are refusing because although I have sent the original mortgage offer certificate from Abbey they want the actual offer rate and the reasons why they refused.
I have approaced Abbey who said they would not have this information after all this time.
It seems so unfair.
Does anyone think it is worth my while persuing them?
I will be grateful for any advice.
I am now in a position where I am going to have to sell my house again and move into a housing association property after struggling for nearly 30yrs to pay a mortgage because my fixed term will finish next year and the rates will be so high
Sorry for rambling.
