I've just had the shock of the week, both my cards were declined and when i went to the ATM, it refused to let me access my balance.
AIBU to grossely misuse AIBU and split an infinitive in my haste to let you know that if your HSBC card has been declined, it is most probably not because someone's hacked your bank of your account is mysteriously empty - it's because they're having 'global system errors' according to the lady on the HSBC helpline. It too me ages to get through so thought I would pass it on! They said it would be sorted asap.
