FNB ***** department call with bad attitude

***** department number ***, the lady is name is GUGU, who answered my call was very rude, and she even swear at me, because i answered a verification question incorrect(due to bank has not update my details). finally i request to speak to the supervisor who solved our issue which we satisfied. we are very disappointed and sad that such a beloved bank has someone with such bad attitude and service standard toward their client to work there, and i was a victim of ***** case, i have just been through a sad case of the card *****, but i also have to go through a bad service call! FNB, please keep your client satisfy and happy,especially the client who was just suffered from the *****, and you should make them comfort, not another damage
