santander credit card incorrect balance

[wjwren]

My partner has a 123 credit card - the balance on the card is very high - more than she normally spends on the card. She returned some items of clothes couple of weeks ago and the refunds are shown on the card but the balance still remains the same. She phoned up Santander and the bloke on the line didnt know why that was - I asked him to send out a paper copy and il check. Today I looked at my mothers 123 account and same issue. Anyone else shed any light?
