You can get a credit report from a company such as Experian which sends you your credit history and where this problem is probably showing up. You can then write to them explaining the circumstances, as I recall they then have to get the credit card provider to agree to it, but it's possble to have it rectified (provided of course you have paid it off now, and although it was 14p it's probably racked up charges, interest, no-payment fees, on top of the original outstanding balance....).
