I have a catalogue that I go to the limit on through necessity in a bad time.
I managed to pay maybe 40% off it but then circumstances went down hill and I was only able to make minimum payments.
The items I had bought on interest free ran out of the free period so 40% interest was added to some large value items :(
So my credit limit was xxx and because of the added 40% interest I ended up OVER my limit.
Obviously all this points to me struggling but managing to pay minimum.
I logged on today to make my monthly payment and they have DOUBLED my credit limit. 
I'm going to call and ask them to reduce it tomorrow.
But I won't lie... with Christmas coming up part of me thought 'oh! ...I might see what they have...'
But it's a false economy of course.
But AIBU to think it's really bad of them to do that? I know it's a buisness but it's preying on people who can't afford things outright and are obviously struggling.
I know it's my own responsibility to manage my money but a lot of people on a low income get dragged into the trap so easily and it's so hard to escape.
Guess I'm just ranting.
