Heads up on mis-sold payment protection insurance guys.
Some time ago I was told quite categorically by my bank that I not only had no cause for complaint, but that they had no record of my transactions with them.
The shutters for such claims are about to come down so do what I did recently, and put it in the hands of a recommended professional as now the bank has suddenly found those records "surprise surprise", and I'm in line for a £3k plus payout. The agent takes a share of that of course but hey, it's better than a poke in the eye.
