FNB confused, no auditablity and pathetic customer service

FNB credit card was suddenly declined and got sms that the card is invalid. Phoned number on back of card - no connection as the card services contact number has been disconnected. Attempted to phone my personal banker 3 times. Each time as the banker answered, the call was dropped. With up-front verification and wait time this process took 20 minutes. Went onto SecureChat in the FNB app. Took me 1 hour and 30 minutes ****erally !) to establish: my card had been cancelled but no-one could tell me by whom or why. When I checked in my CC profile the card still had "Active" status . One agent told me that a new card had been issued....another told me that no new card had been ordered.... eventually got a new card ordered. Time to transfer my banking to another FS provider.....
