A similar situation here in that it was a battle of 6+ years but the tracker was not reinstated as the mortgage had been redeemed and the bank in question said that they couldn't reinstate it.
While a small amount of compensation was given, it didn't nearly amount to the value of the tracker, stress(and was it ever stressful), opportunity cost of having the money at the time. I had also wanted to move house during the period but my hands were tied while the case dragged on and subsequently house prices have doubled. I am back on the hunt for proper compensation in this case
