Hi I was in a similar position to yourself after the CSA really screwed up and virtually made me bankrupt, even though I have a letter from them saying "sorry" it didn`t alter the fact that I missed some credit card payments and Hey Presto "A bad credit rating" through no fault of my own came my way. After applying with no success from a few credit card companies I applied to Barclaycard and they accepted me on a £200 limit initially which was great as I could then buy items on the internet.
BUT BEWARE THE INTEREST RATE IF YOU DO NOT PAY OFF THE BALANCE IN FULL EACH MONTH IS 29.9% APR
But I always pay off in full and get charged NO INTEREST I am just glad that I can have a credit card for my online transactions.
I have been with them for 3 years now and my limit is now £600 but I always pay off in full to avoid the charges, I am re-building my credit rating slowly and hope soon to be able to access a better APR card but I say THANKS to Barclaycard for helping me on my way.
Hope this helps
Kevin
