certainly going back a few years (not sure now) but my credit cards were regularly having the amount available increased by the card issuer.... wihout a request,
the rule was here are the available funds..you tell us if you dont want the facility..
default selling i believe is the term,
i have three credit cards with available credit of £13K, £11K and £7.5K,
in the more recent climate if i was to 'max' these the payments would be worryingly high,
and for many the repayments unaffordable
who said the banks only have themselves to blame?
