Help/advice on store cards/catalouge debt please

Not sure if this is the correct place but can't find any where better. 
I have had an account with JD Williams for a couple of years. There is a small balance of 250 at the moment. 
About 3 weeks ago they wrote to me to say my limit was been increased to 1500,all payments have been on time since the account was opened. 

This week a letter arrived telling me they viewed me as an "Increased risk" and the interest rate was going up to 59.9%.

I have called them to ask for the reasoning around this, I may as well have asked the dog!. 
I am aware that if credit card companies take this action you have the right to pay the debt off at the old rate, I can't find anything regarding catalogue accounts. 

Obviously the sensible thing to do is to pay it off and never deal with them again, I'm not sure how doubling the interest rate of a customer they see as a risk makes it more likely that they will pay, I understand the concept of risk based pricing but it does seem to defy logic. 

If anyone has any knowledge around this I would be very grateful for your advice. 

Thanks

Well you could complain the them on 0345 026 3899.
Using the basis that they increased your limit to £1500, but you have not said from what.
Then 2 weeks later state you are a increased risk.
They can't have it both ways.
