Interesting reading through this thread, thought I'd add my experience.
I had a letter from my bank, Lloyds, 3 years ago telling me I was due a PPI refund but I had to contact them to make a claim! Don't see why they couldn't just give me my refund if they knew I was eligible........
Anyway I made the call and fortunately they rang me back as after an hour or so on the phone that was my application submitted.
I am pleased to say it was time well spent as I received a cheque for nearly £2,000!!
Ever since then I have considered looking into any other possibilities I may have, after all nothing ventured nothing gained, but have nevr quite gotten round to it - that is until last Tuesday when I finally submitted 2 claims through Resolver, 1 to Egg & 1 to GE Money, as I had found all the documentation which I thought was required.
Now, having come across this thread, I shall be sending my DSAR to any finance companies, banks etc who I have had dealing with in the past and just wait for the result
Thank you to everyone but especially
