Yet Again

Approximately 2 weeks ago , my debit card was blocked without warning whilst at supermarket and trying to use it as a debit card.... I called the number provided, and they said it was active after updating FICA details. 2 days later , it was blocked again .. and twice since then ! No warning, no call , just blocked ..an absolute disgrace on their behalf.. I am changing bank as soon as I receive new ID .. This should be LNB ...Last national bank
