Endless hassles from FNB

FNB is just not able to get anything right. We lost the petrol card last year - they issued a replacement THAT WORKED WITHOUT A PIN! No security whatever. When they cancelled that, I app**** for a Credit card type petrol card. That took 2 months to get. First use - "invalid card number". Two weeks later, that was fixed. Next use - Limits exceeded. Is FNB able to do ANYTHING? Banking certainly isn't one of their abilities.
